Channel steel

H-shaped steel is a new type of economical construction steel. The section shape of H-shaped steel is economical and reasonable, and the mechanical properties are good. When rolling, the extension of each point on the section is relatively uniform and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large section modulus, light weight, and metal saving. It can make buildings The structure is reduced by 30-40%; and because the inside and outside of the legs are parallel, and the legs are at right angles, they can be assembled and combined into components, which can save welding and riveting workload by up to 25%. It is often used in large buildings (such as factories, high-rise buildings, etc.) that require large bearing capacity and good section stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.

What kind of problems exist in processing stainless steel flanges and how to solve them?

Weld defects: The weld defects of stainless steel flanges are serious. If manual mechanical grinding is used to make up for it, the resulting grinding marks will cause uneven surfaces and affect the appearance; uneven passivation of grinding and polishing: manual grinding and polishing After pickling and passivation treatment, it is difficult to achieve a uniform and consistent treatment effect for workpieces with large areas, and it is impossible to obtain an ideal uniform surface. It also has the disadvantages of working hours and high cost of auxiliary materials;

What are the anti-corrosion pipeline materials and what are their uses

The materials used for pipeline anti-corrosion are directly related to the quality of pipeline anti-corrosion. Therefore, when anti-corrosion is carried out, the raw materials must pass the test. Different anti-corrosion materials require different raw materials. 1. The main raw materials used in 3PE anticorrosion are polyethylene and polypropylene. 2. Epoxy resin anticorrosion mainly uses epoxy resin composite material coating, phenolic epoxy coating and polymer composite material.
