321 Stainless steel tube Price in China ,Manufacturer of 321 Stainless Steel tube
Mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless heat resistant steel seamless steel tube, these often under high temperature and high pressure boiler tube, tube in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance,
And has good structure stability, hydraulic support tube.
The 321 stainless steel pipe is a long strip of steel with a hollow section and no seams around it.
The steel pipe has a hollow section, a large number of used as a fluid pipeline, such as the transportation of oil, natural gas, gas, water and some solid material pipelines.
Seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, pipe jacking 16MN seamless pipe.
