Stainless steel pipe is a kind of hollow long round steel, which
is mainly used in industrial transportation pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument, etc., as well as mechanical structural components. In addition, when the bending 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. It is also commonly used as furniture and kitchenware.
