Stainless steel seamless pipe is a long strip of steel with a hollow section and no joints on the periphery. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, its processing cost will rise substantially. Seamless steel pipes are tubular sections or hollow cylinders, usually but not necessarily circular cross-sections, and are mainly used to transport flowable substances-liquids and gases (fluids), slurries, powders and small solids.
There are various methods of manufacturing and producing pipes. Welded type, seamless type and other types have different uses and have different mechanical properties. The absolute roughness of stainless steel seamless pipe is smaller; it means higher dimensional accuracy. This is useful in sensitive applications and does not require much processing after production. Seamless pipes are usually cold drawn, while stainless steel welded pipes are produced by welding. Stainless steel Erw tubes are resistance welded and are made by welding long metal bars into a cylindrical shape.
Seamless stainless steel pipes have been widely used in petrochemical, boiler, nuclear power, machinery, shipping, water conservancy and other industries.
Ferritic stainless steels are classified into the 400 series, with a chromium content of usually 10% to 30%, and are usually selected for their excellent corrosion resistance and high temperature oxidation resistance. Ferrite has higher strength than carbon steel and has advantages in many applications that require thinner materials and reduced weight (such as automotive emission control systems). They cannot be hardened by heat treatment and are always magnetic. Typical applications of ferritic stainless steel include petrochemicals, automotive exhaust systems and decorations, heat exchangers, furnaces, household appliances and food equipment.
