Application characteristics of I-beamAlloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, 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.Vann,There are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use, if in normal working environment, the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above, and it has been used safely for about years. It can be seen that its service life is very long. Of course, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used,I-beam features: the content of chromium carbon alloy is -%, and the macro hardness is - HRCIn 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, 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.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.

I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, there is the low cost of metal.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties weldability and structural size.Installation requirements,The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the section is quite different, 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.→ compared with the concrete structure the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.

The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore,Vann15CrMoG high pressure alloy pipe, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be further expanded.Credit guaranteeWhen selecting I-beam in structural design,VannHow much is 12Cr1MoVG alloy tube per ton, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. Spiral welded steel pipe (sy- for pile is made of hot-rolled steel strip coil as pipe blank, often warm spiral forming,VannAlloy tube, double-sided submerged arc welding or high-frequency welding. It is used for foundation pile of civil building structure wharf, bridge, etc.Difference and application description between H-beam and I-beamVann,b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.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'.
