Application

Stainless steel pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instrument etc., such as industrial pipeline and mechanical structure parts and stainless steel pipe with low leakage rate, good water, corrosion resistance and thermal insulation performance is strong, so it is the best drinking water delivery pipes. And, stainless steel pipe has high tensile strength, high ductility and toughness, low coefficient of thermal expansion, corrosion resistance, wear resistance, long service life, light weight and recyclable advantages, so it is often used as a gas pipeline. Finally, because of the stainless steel pipe because of high tensile strength, good wall finish, wear resistance and other advantages, so it is widely used in the decoration industry.
