Automobile industry
The main use of stainless steel is the exhaust system, accounting for more than 1/2 of the total automobile stainless steel consumption, 80% for ferritic stainless steel. The exhaust gas produced by the automobile engine is discharged from the muffler through the exhaust gas intake pipe, front pipe, hose, converter and center pipe. Exhaust system commonly used steel 409L, 436L and so on. Automobile mufflers mainly use stainless steel welded pipe. It is estimated that stainless steel pipes used in automobiles account for about 1.5% of the total downstream use of stainless steel pipes, and the use ratio of stainless steel seamless pipes and welded pipes is about 2:1.

The petrochemical industry includes the fertilizer industry
The demand for stainless steel pipe is great, the industry mainly uses stainless steel seamless pipe, specifications include: 304, 321, 316, 316L, 347, 317L, etc., the outer diameter is about 18-￠610, the wall thickness is about 6mm-50mm (generally the selection of specifications in Φ159mm above the medium and low pressure pipeline), the specific application field is: Furnace tube, material conveying tube, heat exchanger tube, etc.

Water and gas and other fluid transport
Stainless steel pipe and its water transport equipment, is the world's most advanced basic water purification materials, its strong corrosion resistance, cast iron pipe, carbon steel pipe, plastic pipe, etc., can not be compared with.

Water preparation, storage, transportation, purification, regeneration, desalination and other water industry the best material selection. The annual demand is about 25,000 tons.

Equipment manufacturing and maintenance
Annual consumption of stainless steel pipe more than 20000 tons. This kind of industry mainly uses sanitary or antibacterial grade 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, in the kitchen equipment, food industry workbench and utensils, medical instruments, tableware in daily life and hanging towel bracket, freezer bracket and other fields of demand is increasing.
