Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used in furniture and kitchen utensils.

Material classification

Stainless steel pipes are 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, plated and coated 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. The outer diameter of the steel pipes currently produced ranges from 0.1 to 4500 mm, and the wall thickness ranges from 0.01 to 250 mm. In order to distinguish their characteristics, steel pipes are usually classified according to the following methods.

Application Scope

Stainless steel pipe is an economical cross-section steel material and an important product in the steel industry. It can be widely used in life decoration and industry. Many people on the market use it to make stair handrails, window guards, railings, furniture, etc. The most common materials are 201 and 304.
