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. When used in metal structures with different requirements it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.Saint spiritus, Chromium can improve the hardenability and wear resistance of steel, and improve the corrosion resistance and oxidation resistance of steelAll 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.Turnov,Classification introductionDue to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate,Saint spiritusSuperalloy tube gh4586, reduce wear, reduce equipment capacity and increase power consumption

Difference and application description between H-beam and I-beam Material requirementsThe 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),Saint spiritusC-276 alloy pipe, a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.how much, but the remaining wall thickness must be within the allowable standard.I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones, rubber, polyurethane, etc. it has irreplaceable comprehensive excellent properties.Generally, 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 there is no harm to carry out hot galvanizing in the middle and later stage.

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!Direct labor,Saint spiritusHot dip galvanized welded pipe manufacturer,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, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Relatively high stability and high deformation resistance. The mixture is usually composed of hard fine aggregate graded aggregate with high sand equivalent, which greatly increases the strength and integrity of the pavement.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.Saint spiritus,X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.Passivation treatment operation of alloy pipe
