Seamless Steel Pipe Description
Seamless steel pipe Description
Stainless Steel Seamless Pipes / Tubes are widely used in commercial and industrial fields, especially fluid transportation. With appropriate processes, they have superior performance in high pressure, high strength, and corrosion resistance.Seamless stainless steel pipe is used in applications where high temperature strength and superior corrosion resistance are critical. Further, stainless steel is easy to clean and doesn’t tarnish.
Seamless steel pipe Classification:
1、Stainless steel pipe is divided into hot rolling, hot extrusion and cold drawing (rolling).
2、According to the different microstructure of stainless steel divided into half ferritic half martensitic stainless steel tube, martensitic stainless steel tube, austenitic system stainless steel tube, austenitic - ferritic iron series stainless steel tube.
