Stainless Steel Pipes And Tubes
The stainless steel tubes are widely used in petroleum, chemical, nuclear, thermal power generation, non-ferrous metal smelting, shipbuilding, food processing and other industries.
Usually stainless steel tube is divided into welded pipe and seamless pipes. The seamless stainless steel tube and pipe more solidity and reliability. Therefore, seamless stainless steel pipe is widely used in corrosion medium high (ultra-high) (high) temperature and high pressure environments and other harsh environment.
