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.
