Stainless steel pipe is a hollow elongated round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also commonly used as furniture and kitchen utensils.
1. Automotive industry
Stainless steel is mainly used in the exhaust system, which accounts for more than 1/2 of the total amount of stainless steel used in automobiles, and 80% is ferritic stainless steel. The exhaust gas produced by the car engine passes through the exhaust gas intake pipe, front pipe, hose, converter, center pipe and finally flows out of the muffler. Exhaust system commonly used steel grades are 409L, 436L and so on. Automobile 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, while the ratio of stainless steel seamless pipes and welded pipes is about 2:1.
2. Petrochemical industry including chemical fertilizer industry
The demand for stainless steel pipes is extremely high and the industry mainly uses stainless steel seamless pipes. The outer diameter of the steel pipe is about ￠18-￠610, and the wall thickness is about 6mm-50mm (generally, medium and low pressure pipelines with specifications above Φ159mm are selected). The specific application fields are: furnace tubes, material conveying tubes, heat exchanger tubes, etc.
3. 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, with strong anti-corrosion performance, which cannot be compared with cast iron pipes, carbon steel pipes, plastic pipes, etc. Stainless steel pipe is the best material for water industry such as water preparation, storage, transportation, purification, regeneration, and seawater desalination. The annual demand is about 25,000 tons.
4. Equipment manufacturing and maintenance
This type of industry mainly uses sanitary or antibacterial stainless steel pipes, and the annual consumption of stainless steel pipes is more than 20,000 tons. The sanitary seamless pipe made of imported SUS304 and 316L can meet the special requirements of various media in the fields of food and biopharmaceuticals. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial properties, and its demand is increasing in kitchen equipment, food industry workbenches and utensils, medical equipment, tableware and towel hanging racks in daily life, and refrigerated cabinet brackets.
