202 Stainless Steel Square Pipe

Product description:

Stainless steel square pipe is a hollow long strip of steel, because the section is square, so it is called square pipe. A large number of pipelines used to transport fluids, such as oil, natural gas, water, gas, steam, etc., in addition, when the bending resistance and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.
