Stainless steel pipe

Stainless steel is a long hollow circularsteel products, mainly used in petroleum, chemical, medical, food, lightindustry, machinery and other industrial pipeline instrumentation andmechanical structural components. In addition, bending, torsional strength,lighter, so it is widely used in manufacture of mechanical parts andengineering structures.
