Application Requirements Of Stainless Steel Pipes

Auto industry
Stainless steel is mainly used in the exhaust system, accounting for more than 1/2 of the total stainless steel consumption in automobiles, and 80% is ferritic stainless steel. The exhaust gas generated by the car engine passes through the exhaust air intake pipe, front pipe, hose, converter, center pipe and finally flows out of the muffler. Commonly used steel types for exhaust systems include 409L, 436L, etc. Car mufflers mainly use stainless steel welded pipes. According to estimates, the stainless steel pipes used in automobiles account for about 1.5% of the entire downstream consumption of stainless steel pipes, and the usage ratio of stainless steel seamless pipes and welded pipes is about 2:1.
Petrochemical industry including fertilizer industry
The demand for stainless steel pipes is huge. The industry mainly uses stainless steel seamless pipes. The specifications include: 304, 321, 316, 316L, 347, 317L, etc., with an outer diameter of around ￠18-￠610 and a wall thickness of 6mm-50mm. Left and right (usually medium and low-pressure transportation pipes with specifications above Φ159mm are selected). The specific application areas are: furnace pipes, material transportation pipes, heat exchanger pipes, etc.
Fluid transportation such as water and gas
Stainless steel pipes and their water delivery equipment are the most advanced basic water purification materials in the world today. They have strong anti-corrosion properties that cannot be compared with cast iron pipes, carbon steel pipes, plastic pipes, etc.
The best material for the water industry such as water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand is approximately 25,000 tons.
Equipment manufacturing and repair
The annual consumption of stainless steel pipes is more than 20,000 tons. This type of industry mainly uses sanitary or antibacterial grade stainless steel pipes. Hygienic seamless pipes made of imported SUS304 and 316L can meet the special requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial properties. The demand for it is increasing in the fields of kitchen equipment, workbenches and utensils in the food industry, medical equipment, tableware and towel hanging racks in daily life, and brackets for refrigerators.
