Stainless Steel Pipe

What is Stainless Steel Pipe?

Stainless steel pipe is a hollow long steel made of stainless steel. Because of its excellent corrosion resistance, it is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structure components. In addition, when bending and torsion strength is the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and also commonly used in the field of decoration. Stainless steel pipe has many kinds, different uses, different technical requirements and different production methods.

Stainless steel pipe is divided into seamless pipe and welded pipe according to production mode. Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe. Cold drawn and cold rolled pipe is the secondary processing of steel pipe.

Stainless steel pipe can be divided into circular pipe and special-shaped pipe according to cross-section shape. There are rectangular tube, rhomboid tube, elliptical tube, hexagonal tube, octagonal tube and various section asymmetric tube. Special-shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the circular tube, the special-shaped tube generally has a large moment of inertia and section modulus, and has a large bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.

It can be divided into oil well pipe (casing, tubing and drill pipe, etc.), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas bottle pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, petroleum cracking pipe) and ship pipe, etc.
