Wenzhou finish stainless steel sanitary pipe means is a hollow elongated cylindrical steel material, stainless steel tubes suitable for sanitary finishing piped fluid. Wenzhou stainless steel sanitary pipe finishing mainly used in the pharmaceutical, dairy, beverage plants, medical device, chemical plants, precision machinery factory. On the national economy in many fields of food, beer, water, bio-engineering, chemical engineering, air purification, aerospace, nuclear industry and other industries widely used stainless steel sanitary pipe finishing. Wenzhou stainless steel sanitary pipe finishing features: wall thickness of 1, the use of stainless steel sanitary pipe tank or pressure vessel manufacture than conventional austenitic 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 sanitary pipe finishing with good resistance to localized corrosion, its resistance to corrosion and abrasion are superior corrosion fatigue of austenitic stainless steel. 5, stainless steel sanitary pipe has the ability to finish excellent resistance to stress corrosion cracking, even the lowest-containing alloys are capable of duplex stainless austenitic stainless steel is higher than the resistance to stress corrosion cracking, especially chlorine ions in the environment in.
