316L 321 sus stainless steel pipe with customized size with
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

Chemical Composition about stainless steel Tube
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.
