Automotive industry:Stainless steel is mainly used in the exhaust
system, accounting for more than 1 / 2 of the total consumption of
automotive stainless steel, and 80% is ferritic stainless steel.
The exhaust gas generated by the automobile engine flows out of the
muffler through the exhaust gas inlet pipe, front pipe, hose,
converter and central pipe. The commonly used steel grades of
exhaust system are 409L, 436l, etc. Stainless steel welded pipe is
mainly used for automobile muffler. It is estimated that the
stainless steel pipe used in automobile accounts for about 1.5% of
the consumption of stainless steel pipe in the whole downstream,
while the proportion of stainless steel seamless pipe and welded
pipe is about 2:1.
Petrochemical Industry
chemical fertilizer industry
There is a great demand for stainless steel pipes. Stainless steel
seamless pipes are mainly used in this industry. The specifications
include 304, 321, 316, 316L, 347, 317L, etc. the outer diameter is
about ￠ 18 - ￠ 610 and the wall thickness is about 6mm-50mm
(generally, the specification is Φ Medium and low pressure
transmission pipeline above 159mm), and the specific application
fields are: furnace pipe, material transmission pipe, heat
exchanger pipe, etc.
Fluid transportation such as
water and gas
Stainless steel pipeline and its water transmission equipment are
the most advanced basic water purification materials in the world.
They have strong anti-corrosion performance, which can not be
compared with cast iron pipe, carbon steel pipe and plastic pipe.
The best material for water industry, such as water preparation,
storage, transportation, purification, regeneration and seawater
desalination.The annual demand is about 25000 tons.
Equipment manufacturing and maintenance
This kind of industry mainly adopts sanitary or antibacterial
stainless steel pipe. The sanitary seamless pipe made of imported
SUS304 and 316L can meet the special requirements of various media
in the field of food and biopharmaceutical. Antibacterial stainless
steel has the advantages of stainless steel and good antibacterial
performance. The demand for antibacterial stainless steel is
increasing in the fields of kitchen equipment, workbench and
utensils in food industry, medical equipment, tableware and towel
hanging support in daily life, bracket of refrigerator and so on.
The annual consumption of stainless steel pipe is more than 20000
tons.
