Application Scope

Stainless steel pipe is an economical cross-section steel 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 railings, window guards, furniture, etc. The two common materials are 201 and 304.
Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, meducal, 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 structures. Also often used as furniture and kitchen utensils.
