When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCCharatenango,The grid spacing size and number of reinforcement of electric welding reinforcement mesh are correct, which overcomes the phenomenon of large spacing size error and missing binding and buckle of binding quality caused by manual placement of reinforcement in traditional manual binding. The welded steel mesh has high strength and good elasticity. When pouring concrete, the steel bar is not easy to be partially bent and does not change. Because it is considered that the longitudinal and transverse steel bars are spot welded into a mesh structure, so as to achieve the goal of side-by-side average stress and bonding anchor.a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Bhai Pheru,When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage.

Small longitudinal crackHeating surface pipes, economizers, superheaters, reheaters, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)

Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore most seamless steel pipes are round steel pipes.The electric welding reinforcement mesh can reduce the damage and consumption to the reinforcement processing process. According to statistics, after deducting the steel consumption increased by unit lapping, it can also save about % of the steel. After it is transported to the site according to the construction degree of the project, it can be hoisted to the working face. There is no need to set a reinforcement processing site on the site, which saves the site and increases the management level of the site. At the same time, it can also solve the problems of noise pollution caused by straightening reinforcement.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsWork courses,I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Requirements of alloy tubes for low and medium pressure boilersWhether I-section steel is ordinary or light because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different,Charatenango45# thick wall seamless pipe,CharatenangoHow much is DN25 galvanized pipe per meter, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.

Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.Honesty and mutual benefitSome applications of I-beam:In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time, even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Charatenango, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.According to the theory of steel structure, the I-beam flange should be stressed, that is

This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely used Judged as failing.

What is the stainless steel passivation of alloy pipe?original→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.The use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required, the concrete can be irrigated, eliminating the links such as on-site cutting, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Centrepec,The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam which is easy to lose stability for load-bearing columns.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃

Key technical characteristics of alloy pipe: H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Aguilares,The chemical composition of cold-rolled ribbed strip is the same as that of hot-rolled smooth round strip. It is rolled at room temperature with hot-rolled smooth disc strip, which is called cold rolling. Due to the reorganization of steel crystal structure by cold rolling process, high tensile strength (LL, ll, ll, etc.) is obtained which has poor ductility and cannot be welded. If there are double-sided ribs and three-sided ribs,I-beam the specification allows LL to be used as stirrup. The design value of strength is limited to n / mm?.Introduction to product knowledge of alloy pipe:Arrah, also known as steel beam, is a long strip of steel with I-shaped section.

It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.

The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Galvanized pipes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding,Aguilares110 galvanized pipe 6 meters how much is a piece, solar power generation support, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall automobile chassis, airport, boiler construction, highway railing, house construction, pressure vessel, oil storage tank, bridge, Hoisting and transportation machinery and other welded structural parts with high load. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Recommendation and consultation,According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, whose codes are Hz, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.I-beam, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Pass design

The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy,Aguilares2520 stainless steel seamless pipe manufacturer, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace.

Fix the plan product workpiece or preformed vacancy on the rotating journal,AguilaresCold drawn seamless pipe manufacturer, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.The third is the welding machine, which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.The key purpose of grinding and polishing alloy pipe is to moisten the surface,Alloy steel pipe is a new type of seamless steel pipe connection pipeline.

The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality. Remove defective pipes within the allowable length.

All the cracks occur at -mm away from the edge below the alloy pipe,Akajutra15CrMo alloy pipe factory, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape. Carbon: the higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughnessBecause alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Safety production,When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data alloy pipe is widely used. In many projects, we will apply it so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know: Remove defective pipes within the allowable length.Introduction to product knowledge of alloy pipe:

The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore,When it is used for ground heating and hot spring transportation which exceeds the welded composite section.Management Department, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Steel pipes can be classified by their models:I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Akajutra,The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.It is widely used in various fields of national economic construction, such as buildings, bridges power stations, oil drilling platforms, highways, subways, steel structure plants and large warehousesThe production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.

Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, etc.I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.Ayutepke, According to the diameter of the pipe, the pipe with small diameter can only be welded on one side and the technician can drill into the pipe to weld on both sides. Single side welding requires the welder&#;s technology, which can be formed by welding two on one side. Through the steel ball test, it can ensure that the cross-sectional area passing capacity and weld formation meet the design requirements.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal,Ayutepke20# thick wall seamless pipe, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Kotri,The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be further expanded.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, this cognition is wrong. H-beam and I-beam are different in shape!

Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process,AyutepkeHow much is 20 steel bars per meter, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Welded thin-walled pipe: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture, decoration, fence and so on.Stages needing attention in the production and manufacture of alloy tubesFree consultation,I-beam, also known as steel beam is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis. Frame line crack

The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy,However, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.Hardness of reinforcement construction of reinforced mesh on concrete bridge deck; Including key lime mixing and packaging materials, you need to pay attention to calculating the size of the building,AyutepkeHow many inches is welded pipe 273, and the calculated specifications must meet the quality standards and construction standards.Application characteristics of I-beamAyutepke,Application characteristics of I-beamAlloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production manufacturing and key marketing of alloy pipe, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.I-beam That is, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.

I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill,Los Angeles UnionWhich is easy to use for steel bar software, profiled steel plate, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete which is convenient for settingLos Angeles Union,In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.I-beam, whether ordinary or light,Los Angeles UnionIncoloy825 alloy pipe, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Denov,Classification introductionI-beam also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.

The utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required, The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement,Los Angeles UnionHow much is the I-beam of 20, without hook.What are the uses of I-beam?Where can I find it?, The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.

Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Scheme customization,Pass design Cleaning: first, clean the grease, dust and other substances attached to the surface of the galvanized pipe after cleaning.The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters and the compression amount is adjustable; Straighten the width with staggered straightening wheels.Los Angeles Union,Passivation treatment operation of alloy pipeH-section steelWelded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.

Methods of exerting efficiency in application of C-section steelAccording to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Boca Chica ,The production of plastic impregnated welded steel wire mesh is to immerse the formed welded steel wire mesh into a stone groove filled with PVC powder. The dry forming process is complex and the cost is much higher than that of spray welded mesh. Due to different application ranges and different uses the choice is expensive or cheap, which needs to be determined according to its actual use.What is the stainless steel passivation of alloy pipe?Varde,Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore,Boca Chica How much is the customized I-beam, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, it will eventually lead to bad harm to the product quality.However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.In order to make the welded pipe have the required mechanical, physical and chemical properties,Boca Chica Inconel 601 alloy pipe, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.According to the section shape, the steel pipe is divided into:According to the theory of steel structure, the I-beam flange should be stressed, that is,The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.

Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Interpretation and observation,Some applications of I-beam:External steel bonding reinforcement method is a more traditional reinforcement method. The utility model uses an adhesive to paste the steel plate or reinforcement mesh on the cracked part of the wall to achieve the purpose of reinforcement. The commonly used adhesive is usually epoxy resin. This method is simple and fast in construction and has little impact on production and life. Basically, the bearing capacity of the wall can be greatly improved without changing the shape and internal use space of the components. It is mainly applicable to the reinforcement of walls that do not allow to increase the section size of original components, but can greatly increase the section bearing capacity.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Boca Chica , Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by few station mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore, it is widely usedAlloy pipe is a spiral seam seamless steel pipe which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.

What are the uses of I-beam?The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,hairHow much is a ton of welded pipe, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.hair, Pure zinc layer is a plastic zinc layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is flexible. Galvanized pipe is widely used in architecture. This product must have been seen by everyone. However, there are many types of it. When you buy it, you should also find out which one you need. The reason why it is favored by everyone in the market is inseparable from its advantages. Next, Xiaobian will lead you to see the advantages of galvanized pipe.What should we pay attention to in the production of alloy pipeTasboget, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape. Miscellaneous scab

The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.Seamless pipe is a long steel with hollow section and no joints around it. There are more than production plants under more than companies in more than countries producing seamless pipes, including more than plants under more than companies in countries.I-beam is widely usedassets,Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Stages needing attention in the production and manufacture of alloy tubesDefects of alloy pipe and solutions:

Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition,hair12Cr1MoV alloy pipe, when the circular cross section bears the internal or external axial working pressure the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.Which one is better,→ I-beam can be processed into T-beam, which greatly meets the needs of engineering design and manufacturing. Fabrication and installation of pipe support:I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.hairAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, which exceeds the welded composite section.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.

The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Chachuvapa,In order to ensure the welding quality of welded pipe,ChachuvapaHow much is 18 I-beam, the forming roll, guide roll, extrusion forming roll and sizing roll must be adjusted once, and then the most important thing is to adjust the closing plate hole guide roll and extrusion forming roll of the forming roll. Among them, the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe, reducing the edge widening, controlling the edge springback of the finished rolled pipe,ChachuvapaHow much is 50 galvanized pipe, and ensuring that the weld is vertical without screwing into the extrusion roll.Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Siuna,After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Key technical characteristics of alloy pipeI-beam also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.

After the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, the solution temperature is ~ ℃, and the solution time is min. Then dry.Cutting machine, electric welding machine, polishing machine, etcI-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.where,Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Alloy pipes can be used for heating (cooling) projects.

Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.install, Hot hole breaking cold rolling method. This method is dominated by expansion and expands vertical sliding and skew rolling. The former one is mainly cold rolling by relatively limited mandrel mill, cold rolling by three high limited mandrel mill and cold rolling by fluctuating mandrel mill. In this way, the advantages of high efficiency, low metal material consumption, excellent product quality and excellent automatic control system are more and more widely used. The competitive advantage of the latter one is low cost and short whole process. It is suitable for the processing and manufacturing of CrMoG alloy pipes with large quantities, small types, multi specifications and high precision. Therefore,Chachuvapa022cr17ni12mo2 seamless pipe, it is widely usedDue to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site,The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number, I-beam has no specific composition and performance series.→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.Key technical characteristics of alloy pipe

→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.In addition to these, the advantages of galvanized pipe are also reflected in some other aspects. For example, its reliability is also very good. Because the combination of zinc coating and steel is good news for metallurgy, it has become a part of galvanized steel pipe on the steel surface. In this way, the durability of its coating is more reliable. And when the zinc coating forms a special metallurgical structure, this structure can withstand mechanical damage during transportation and use. When in use,Compastra asuyaHow much is 219 welded pipe per ton, it also has the advantages of multiple protection. Because every part of the product can be plated with zinc, even in depressions, sharp corners and hidden places can be protected in many ways. It is very convenient during construction. It really saves time and effort. It is because of so many advantages that the utilization rate of this product is very high. And it can avoid the time required for painting on the site after installation. If you want to purchase on your occasion, remember to go to the manufacturer, so that the price will be more favorable.I-beam has wide flange, thin web many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.Scheme customization,Generally,Compastra asuyaAlloy pipe, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, bearing performance and service life.

It is a kind of stronger protection.Application scope of alloy pipeThe side length of I-beam is small and the height is large, so it can only bear the force in one direction.

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Awachapan,Effect of trace elements on properties of galvanized pipe Peak crackBinia Del Mar,It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.

Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc. Because the combination is strong,AwachapanGb5310 quotation of seamless pipe, zinc iron is miscible and has strong wear resistance;Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different,At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange,AwachapanHow much is 2-inch galvanized pipe per meter, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.What is the stainless steel passivation of alloy pipe?

Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different so it can only be directly used for members bent in the plane of their web or form lattice stressed members.install,H-shaped steel groove is deep and thick, and can withstand forces in two directions.There shall be no bending at the welded junction, and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening,I-beam is mainly divided into ordinary I-beam light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.The pickling agent in the pickling process contains many acidic substances,AwachapanMONEL400 alloy pipe, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.

The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Alloy pipes can be used for heating (cooling) projects.Mocha, Material requirementsAlloy tube is widely used in our daily life, which provides us with great assistance.Nicastro,MochaGh3039 superalloy tube,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Whether I-section steel is ordinary or light, because the section size is relatively high and narrow,MochaHow much is the price of I-beam per ton, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.So why is the alloy pipe easy to rust after being pickled and passivated by the software?

Key technical characteristics of alloy pipeThe pipeline shall be positioned according to the drawing design, and the pipeline support shall be prefabricated according to the site conditions. Hang the wire from the th floor down and fix the support.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Honesty and mutual benefitAlloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.GB No. I-beam is in height, in leg width and in waist thickness.

The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, I-beam can also adopt special rolling method.Development Curriculum, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam. It has a thick and dense pure zinc layer covered on the steel surface, which can prevent the steel substrate from touching with any corrosion solution and maintain the steel substrate from corrosion. In general atmosphere, the surface of zinc layer forms a thin and dense zinc oxide layer, which is difficult to dissolve in water, so it plays a certain maintenance effect on steel matrix. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal.I-beam,Mocha16Mn high pressure alloy pipe, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Mocha,Alloy pipes can be used for heating (cooling) projects.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width the more serious the disadvantages.

Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsDehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementIlopango, According to the pipe wall thickness,IlopangoCold drawn welded pipe manufacturer, pipes made of relatively thin materials such as steel strip can be welded with high frequency, and some thin-walled pipes can be welded with shielding gas; Pipes with wall thickness more than mm can be welded by hand.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Meiganga, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is, under the action of thermal stress,IlopangoDirect sales of welded pipe manufacturers, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate shape and chemical composition of the workpiece in the martensitic transformation zone. Miscellaneous scabThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.

Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.High percentage of metal strength.Whether I-section steel is ordinary or light because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Industry management,I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCWhen selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, weldability and structural size.What is the purpose of flat steel

Classification introduction Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.Bono,General welded pipe: General welded pipe is used to transport low-pressure fluid. It is made of qa qa and QA steel. It can also be made of other mild steel that is easy to weld. Water pressure, zigzag, flattening and other tests shall be carried out for steel pipes, and there are certain requirements for surface quality. Generally, and fixed length (or double length) delivery is often required. The standard of welded pipe is expressed in nominal diameter (mm or inch). The nominal diameter is different from the actual. Welded pipe can be divided into general steel pipe and thickened steel pipe according to the specified wall thickness, and steel pipe can be divided into threaded and non threaded according to the way of pipe end.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight.

It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.

Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.

The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank, and welded pipe with different pipe diameter with blank of the same width. However, compared with the straight seam pipe with the same length, the weld length increases by ~ , and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly, while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing, wire drawing is OK. Welded pipe is welded with strip steel, so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories.

Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Bono,Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam.
