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. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Classification introduction→ 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.

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. Because the physical properties of alloy tubes are easy to change and adjust.Where is it, Hot stamping. 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 selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.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.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %
