HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel Tube.Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.

Welded stainless steel pipe referred to as stainless steel welded pipe, commonly used steel or steel band after the unit and mold crimp forming of the steel pipe.Welding steel pipe production process is simple, high production efficiency, variety and specification, equipment investment is less, according to the welding form divided into straight welded pipe and spiral welded pipe.It can be divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen-blown welded pipe, wire bushing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, welded thin-wall pipe, welded special-shaped pipe and spiral welded pipe

321 stainless steel pipe is a kind of long steel with hollow section and no joint around.The pipe has a hollow section and is used in a large number of pipelines for fluid transportation, such as those for oil, natural gas, gas, water and some solid materials.Seamless tube is divided into hot rolled tube, cold rolled tube, cold drawn tube, extrusion tube, 16Mn seamless tubeHigh quality

321 stainless steel pipe seamless steel pipe (gb3087-1999) is used to manufacture hot rolled and cold drawn (rolled) seamless steel pipe of high quality carbon structural steel for all kinds of structure low-medium pressure boiler superheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe, large pipe, small pipe and arch brick pipe.321 stainless steel pipe: 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, the boiler tube by the party under high temperature and high pressure pipe and works 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 have good organizational stability, hydraulic prop.
