It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight

Small longitudinal crackWhether 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.Posarika, Product description of galvanized pipeBecause alloy pipe is a very unique pipe fitting,PosarikaInconel 718 Alloy Pipe, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Velingara, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Remove defective pipes within the allowable length.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress 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.

According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange wide flange and steel pile, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members.

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.

The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.For more, please check,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.
