Product Introduction

Stainless Steel Pipe grades comparison

Stainless steel round pipe is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structural components. In addition, the bending and torsional strength are the same, and the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used for the production of various conventional weapons, barrels, shells, etc.
