Stainless steel pipes and fittings are indispensable materials in modern industry. They have been widely used in many fields because of their excellent corrosion resistance, high strength and light weight. The following is a detailed description of stainless steel pipes and fittings:

According to material classification: stainless steel pipes can be divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, coatings and coatings that save precious metals and meet special requirements. Among them, the commonly used materials of stainless steel pipes are austenitic stainless steels such as 304 and 316L, and duplex stainless steels such as 2205 and 2507.
Classification according to production methods: stainless steel pipes can be divided into two categories: seamless pipes and welded pipes. Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe; welded pipe is divided into straight seam welded pipe and spiral welded pipe.
According to the cross-sectional shape classification: stainless steel pipe can be divided into round pipe and special-shaped pipe. The special-shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes, and various cross-sectional asymmetric tubes.
