Small longitudinal crackAs 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.

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, 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. According to the process, it is divided into arc welded pipe, resistance welded pipe (high frequency and low frequency), gas welded pipe and furnace welded pipe.The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards.

Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.St. Claude,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, flattening and other tests shall be carried out for steel pipes, and there are certain requirements for surface quality.

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.Seamless pipe has a high position in steel pipe, and there are many large factors. The main usage has accounted for more than %, which is applicable to all walks of life. Seamless pipe factories in China are widely produced. At present, the number of factories in China is also increasing every year, which is determined by the nature and production conditions of seamless pipe. The common production processes and processes are more complex.Welded 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.Honesty and mutual benefit 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,St. ClaudeHow much is a 16 cm galvanized 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,

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. If the surface of the welded pipe is rusty we can polish the appearance of the welded pipe with a wire brush to prevent rust.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.

The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency,Under the action of thermal stress, 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, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, 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,LamentinHow much is the price of welded pipe, 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. Cold extrusion.

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:I-beam 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'.Classification introduction

Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.Quality inspection report,According 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. Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh,Saint AnneHow much does I-beam cost per ton, steel mesh, hook mesh, etc., but its cost is much higher, and it is rarely used under normal circumstances Peak crackSaint Anne,Stages needing attention in the production and manufacture of alloy tubes Peak crack Remove defective pipes within the allowable length.

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,Linbei15CrMoG alloy pipe, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.The reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, convenient installation and durability, Skirting plate (edge guard plate), checkered plate guard plate, installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping, Or wrap edges with angle steel, channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.Passivation treatment operation of alloy pipeWord of mouth recommendation,H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, 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.According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile, 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.C-section steel has uniform zinc layer,LinbeiWhere are many manufacturers of welded pipes, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy.

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.Service first,Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement Seamless pipe is resistant to corrosion, acid alkali, high temperature salt and atmospheric environment, impact and fatigue, and the effective life is more than years;The utility model has the advantages that the axial force of the roll is small, the axial movement is small,Linbei,What is the stainless steel passivation of alloy pipe?What are the requirements for alloy pipe construction accessoriesWhether I-section steel is ordinary or light, due to the relatively high and narrow section size, 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.

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. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Texas port,During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer, the temperature difference will be formed, resulting in uneven volume expansion and contraction, resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, the surface layer is compressed and the core is stretched because the cooling volume contraction of the core cannot be carried out freely. That is, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.What should we pay attention to in the production of alloy pipeFranceville,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. 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.H-shaped steel groove is deep and thick, and can withstand forces in two directions.

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, 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.Online consultation,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: Welded steel mesh is aesthetically pleasing.X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam.

Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher,Texas portWhat is the outer diameter of 80 welded pipe, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance,Texas portLarge diameter 15CrMoG alloy pipe, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.Defects of alloy pipe and solutions:As 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 :, 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 defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.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.San Rafael,First, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam, one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment, 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.Power of La,GB No. I-beam is in height,San Rafael42CrMo thick wall alloy pipe, in leg width and in waist thickness.Metallization: refers to the process of penetrating metal atoms into the surface layer of alloy steel pipe.
