→ wide flange and large lateral stiffness. Strong bending resistance.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.Kani á,Galvanized pipe cleaning, east-west derusting, pickling and shot blastingIn order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition,Kani áHot dip galvanized welded pipe factory, 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.Concepcion-de-La-Vega,Some applications of I-beam: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.Stages needing attention in the production and manufacture of alloy tubes

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.Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, it has strong corrosion resistance.I-beam features: the content of chromium carbon alloy is -%, and the macro hardness is - HRCSampling inspection,→ compared with general section steel,Kani áHow much is the price of I-beam per meter, 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 two surfaces of the flange are parallel to each other, making it easy to connect,Kani áPrice of 15CrMoG seamless pipe, process and install. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.

H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, 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, series and models are complete, which is convenient for settingHigh quality and low price,→ compared with the concrete structure, reduce the self weight of the structure by % - %, and reduce the structural design internal force.Galvanized; hot-rolling;H-section steelKani á,It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms vehicles, highways, subways, 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.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.
