Use Of Stainless Steel Pipe
Aug 24, 2022
1. Automobile industry
The main use of stainless steel is the exhaust system, accounting for the total amount of automobile stainless steel 1/2 above, 80% for ferritic stainless steel. Exhaust system commonly used steel 409L, 436L and so on. Automobile mufflers mainly use stainless steel welded pipes. It is estimated that the stainless steel pipe used by the car accounts for about 1.5% of the whole downstream of the stainless steel pipe consumption, and the use of stainless steel seamless pipe and welded pipe ratio of about 2:1.
Petrochemical industry includes chemical 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 in ¢18-¢610, the wall thickness in 6mm-50mm or so (generally choose specifications in φ159mm above the medium and low pressure pipeline), the specific application field is: Furnace tube, material conveying tube, heat exchanger tube, etc.
3, water and gas and other fluid transport
Stainless steel pipe and its water transmission equipment are the most advanced basic water purification materials in the world today, with strong corrosion resistance, which can not be compared with cast iron pipe, carbon steel pipe, plastic pipe, etc.
Water preparation, storage, transport, purification, regeneration, desalination and other water industry best selection of materials. The annual demand is about 25,000 tons.
4. Equipment manufacturing and maintenance
Annual consumption of stainless steel pipe more than 20,000 tons. This type of industry mainly uses sanitary or antibacterial grade stainless steel pipe. The sanitary seamless tube made of imported SUS304 and 316L can meet the special requirements of various media in food and biopharmaceutical fields. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial properties, in the kitchen equipment, food industry workbench.
