I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V,Galvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In new homes, it is forbidden to use cold galvanized pipes as water supply pipes.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.KusA,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 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.Some applications of I-beam:Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.

Application characteristics of I-beam: The vertical of the processed reinforcement bar shall be divided into small sections as required.With the development of steel structure buildings,HyeliaWholesale of galvanized welded pipe,Hyelia304 seamless pipe wholesale, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.Online consultation,Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementI-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.Requirements of alloy tubes for low and medium pressure boilers

The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.Good qualityDetermined 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 % ~ %. Steel pipe with complex section -- unequal hexagonal steel pipe, five petal quincunx steel pipe, double convex steel pipe, melon seed steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.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,Hyelia6. How much is a ton of galvanized pipe, 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.Hyelia, Frame line crackApplication characteristics of I-beamH-section steel
