A554 Stainless Steel Round Pipe 304 304L 316 316L Welded Steel Pipe for Decoration
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.
Description:
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

Application
Stainless steel pipe is a kind of economic cross section steel, is
an important product of iron and steel industry, which can be
widely used in decorative and industrial life, many people on the
market for making stair handrail, protective Windows, railings,
furniture, etc., common are two kinds of material for 201 and 304.
Stainless steel pipes are widely used in petroleum, chemical
industry, medical, food, light industry, mechanical instruments and
other industrial conveying pipes and mechanical structural parts.
According to use can be divided into oil well pipe (casing, tubing
and drill pipe, etc.), line pipe, boiler pipe, mechanical
structure, hydraulic prop, cylinder pipe, geological, chemical pipe
(high pressure chemical fertilizer pipe, oil cracking pipe) and
tube for ships, etc.
In addition, it is also widely used in the manufacture of
mechanical parts and engineering structures in the light of bending
and torsional strength and light weight.
