Expanded information:
Stainless steel pipe use
1, the automobile industry
Stainless steel is mainly used in the exhaust system, accounting for the automotive More than 1/2 of the total amount of stainless steel, 80% for ferritic stainless steel. Exhaust system commonly used steel grades are 409L, 436L, etc.. Automobile muffler mainly use stainless steel welded pipe. It is estimated that the stainless steel pipe used in automobiles accounts for about 1.5% of the entire downstream usage of stainless steel pipe, while the use of stainless steel seamless pipe and welded pipe is about 2:1.
2, the petrochemical industry, including the fertilizer industry
The demand for stainless steel pipe is extremely high, and the industry mainly uses seamless stainless steel pipe, specifications include: 304, 321, 316, 316L, 347, 317L, etc., the outer diameter of ￠18-￠610 or so, wall thickness of 6mm-50mm or so (generally used in Φ159mm or more specifications in the low-pressure pipeline), the specific areas of application are: furnace pipe, material handling pipe, heat exchanger pipe and so on.
3, water and gas and other fluid transportation
Stainless steel pipe and its water transmission equipment, is the world's most advanced basic water purification materials, its anti-corrosion properties, cast iron pipe, carbon steel pipe, plastic pipe, etc., can not be compared with it.
Water preparation, storage, transportation, purification, regeneration, desalination and other water industries, the best choice of materials. The annual demand is about 25,000 tons.
4, equipment manufacturing and maintenance
Annual consumption of stainless steel tube more than 20000 tons. This type of industry mainly uses sanitary or antimicrobial grade stainless steel tube. The sanitary 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 with stainless steel advantages and good antibacterial properties, in the kitchen equipment, food industry benches and utensils, medical equipment, daily life of tableware and hanging towel brackets, refrigerated cabinets, such as trays and other areas of increasing demand.
