In addition, the chemical raw material transmission pipeline has a wide indoor space.Some applications of I-beam:

The flange of H-beam is of equal thickness, 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.The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared and then the heat treatment process of GCrMo was determined.

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, IX and iy are not as good as H-section steel under the premise of equal weight.Alloy 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.

Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.The monthly summary of the real estate industry shows that there is a significant positive correlation between the market sales and the long-term trend of the apparent consumption of galvanized pipe, but there will also be a backwardness of the market in a special stage, there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe, welded steel pipe and so on.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes.
