Application of stainless steel welded pipe in various industries

Stainless steel welded pipe is a hollow long round steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Auto industry

Stainless steel is mainly used in the exhaust system, which accounts for more than 1/2 of the total amount of stainless steel in automobiles. Commonly used steel types for exhaust systems are 409L, 436L, etc. Automobile mufflers mainly use stainless steel welded pipes.

Petrochemical industry

The petrochemical industry has a great demand for stainless steel pipes. The industry mainly uses stainless steel seamless pipes. The specifications include: 304, 321, 316, 316L, 347, 317L, etc. The outer diameter is about ￠18-￠610, and the wall thickness is 6mm -50mm (generally choose medium and low pressure conveying pipes with specifications above Φ159mm), the specific application areas are: furnace pipes, material conveying pipes, heat exchanger pipes, etc.

Transportation of fluids 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 corrosion resistance and cannot be compared with cast iron pipes, carbon steel pipes, and plastic pipes.
