Product Overview：
Stainless steel pipe is a type of steel pipe with strong oxidation resistance and corrosion resistance. It is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments, industrial transportation pipelines, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is relatively light, so it is widely used in the manufacturing of mechanical parts, engineering structures, various conventional weapons, gun barrels, shells, etc. Seamless stainless steel pipe, also known as stainless steel seamless pipe, is made by piercing steel ingots or solid billets into rough tubes, and then hot rolling, cold rolling or cold drawing them. The materials include 201, 304, etc.
