Stainless Steel pipe (Stainless Steel) is a hollow strip of cylindrical Steel, his scope of application as the pipeline of fluid transport, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. Stainless steel pipes are made of acid and heat resistant billets, heated, perforated, sized, hot rolled and cut.
Classification Of Stainless Steel Pipe:
stainless steel seamless steel pipe and stainless steel welded steel pipe (seam steel pipe) basic two categories. According to the outer diameter shape of steel tube can be divided into round tube and special-shaped tube, what is widely used is circular steel tube, but also has a few square, rectangle, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel tube.
Standard of Stainless Steel Pipe
ASTM A312 Austenitic Stainless Steel Pipes for high-temperature and general corrosive service.
ASTM A213 for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
ASTM A269 Austenitic Stainless Steel Tubes for General Service
ASTM A270 for Austenitic and Ferritic/Austenitic Stainless Steel Sanitary Tubes
