Zhejiang stainless steel non-standard thick-walled tube is a long hollow cylindrical steel, stainless steel non-standard thick-walled tube is suitable for transporting fluids, mainly for the petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial conveyor piping and mechanical structural components and the like. Zhejiang non-standard thick-walled tube of stainless steel Features: 1, using non-standard thick-walled pipe wall thickness of the tank or pressure vessel manufacture than conventional austenitic stainless steel 30-50% reduction, help reduce costs. 2, and carbon steel close for connection with steel, has important engineering significance, such as the production of composite panels or linings. Stress corrosion is a common austenitic stainless outstanding problems difficult to solve. 3, no matter under dynamic loading or static load conditions, with higher energy absorption capacity, which structure to cope with incidents such as collisions, explosions and other obvious advantages of duplex stainless steel, have practical value. 4, stainless steel non-standard thick-walled tube has good resistance to localized corrosion, its resistance to corrosion and abrasion are superior corrosion fatigue of austenitic stainless steel. 5, non-standard thick-walled stainless steel tube has the ability to excellent resistance to stress corrosion cracking, even the lowest-containing duplex stainless steel alloy also has a higher capacity than the austenitic stainless steel resistance to stress corrosion cracking, especially chlorine ions environment.
