What industries are stainless steel pipes commonly used in?
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 automobile engine flows out of the muffler through the exhaust gas intake pipe, front pipe, hose, converter, and center pipe. 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.
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, and 321, and 316, and 316L, and 347, and 317L, etc. The outer diameter is around ￠18-￠610, and the wall The thickness is about 6mm-50mm (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.
2. Transportation of fluids such as water and gas
Stainless steel pipes and their water delivery equipment are today's most advanced basic water purification materials. Their anti-corrosion properties are unmatched by cast iron pipes, carbon steel pipes, plastic pipes, etc. It is an excellent choice for water industries such as water preparation, storage, transportation, purification, regeneration, and seawater desalination. The annual demand is approximately 25,000 tons.
3. 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.
