Zhejiang stainless steel sanitary pipe finishing a long hollow cylindrical steel, stainless steel sanitary pipe finishing applies to pipeline fluids, the products are widely used in petroleum, chemical, medical, food, light industry, machinery and other industrial instruments pipeline and mechanical structural components. Stainless steel material selection for acid and heat-resistant grades of steel billet, after heating, piercing, sizing, hot rolling, cutting from. Zhejiang stainless steel tube finishing health advantages are: 1, with wall thickness of duplex stainless steel tank or pressure vessel than the usual 30-50% reduction in austenite, help reduce costs. 2, both under static and dynamic load or load conditions, 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. 3, stainless steel sanitary pipe has good resistance to localized corrosion, its resistance to corrosion and abrasion are superior corrosion fatigue of austenitic stainless steel.
