Tube mill manufacturer:Industrial pipes also include welded pipes and seamless pipes, which are mainly used in engineering structures, various types of pipes, etc.

What are the classifications of stainless steel pipes

1Stainless steel pipes are classified by material

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 bimetal composite pipes, plating and coating pipes to save precious metals and meet special requirements. There are many types of stainless steel pipes, with different uses, different technical requirements and different production methods.

2 Classified by production method

Stainless steel pipes are divided into seamless pipes and welded pipes according to production methods. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, and extruded pipes. Cold-drawn and cold-rolled are the secondary Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

3 Classified by section shape

Stainless steel pipes can be divided into round pipes and special-shaped pipes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, rhombus tubes, oval tubes, hexagonal tubes, octagonal tubes, and various asymmetrical cross-section tubes. Special-shaped pipes are widely used in various structural parts, tools and mechanical parts.

4 Classified by pipe end shape

Stainless steel pipes can be divided into smooth pipes and threaded pipes (threaded steel pipes) according to the state of the pipe ends. The threaded pipe can be divided into ordinary threaded pipe (pipes for conveying water, gas and other low pressure, which are connected by ordinary cylindrical or tapered pipes) and special threaded pipes (pipes for petroleum and geological drilling. Special thread connection). For some special pipes, in order to compensate for the influence of the thread on the strength of the pipe end, the pipe end is usually thickened (internal thickening, external thickening or internal and external thickening) before turning the wire.

5 Classified by purpose

According to the purpose, it can be divided into oil well pipe (casing, tubing and drill pipe, etc.), line pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, petroleum cracking pipe, etc.) ) And ship pipes.

Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering
