Application Requirements of Stainless Steel Pipes
automotive industry
Stainless steel is mainly used in exhaust system, accounting for more than 1/2 of the total amount of automotive stainless steel, 80% of which is ferritic stainless steel. The exhaust gas produced by automobile engine flows out from muffler through exhaust intake pipe, front pipe, hose, converter and central pipe. Common steel grades of exhaust system are 409L, 436L, etc. Stainless steel welded pipe is mainly used in automobile muffler. It is estimated that the stainless steel pipes used in automobiles account for about 1.5% of the total downstream consumption of stainless steel pipes, while the proportion of stainless steel seamless pipes and welded pipes is about 2:1.
Petrochemical industry includes chemical fertilizer industry
There is a great demand for stainless steel pipes. Stainless steel seamless pipes are mainly used in this industry. Specifications include 304, 321, 316, 316L, 347, 317L, etc. The outer diameter is about
Fluid conveying such as water and gas
Stainless steel pipeline and its water conveyance equipment are the most advanced basic water purification materials in the world. Their corrosion resistance is strong. Cast iron pipe, carbon steel pipe, plastic pipe and so on can not be compared with them.
Water preparation, storage, transportation, purification, regeneration and desalination are the best materials for water industry. Annual demand is about 25,000 tons.
Equipment Manufacturing and Maintenance
The annual consumption of stainless steel is more than 20,000 tons. This kind of industry mainly uses sanitary or antimicrobial stainless steel pipe. The hygienic seamless tubes made of imported SUS304 and 316L can meet the special requirements of various media in the field of food and biopharmaceuticals. Antimicrobial stainless steel has the advantages of stainless steel and good antimicrobial properties. The demand for antimicrobial stainless steel is increasing in the fields of kitchen equipment, food industry worktables and utensils, medical equipment, tableware and towel hanger brackets in daily life, refrigeration cabinet brackets and so on.
