Stainless steel pipe is an innovative hollow, long circular steel product that stands out in a myriad of industries. Widely embraced in petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial sectors, it serves crucial roles in transportation and mechanical structural components. With remarkable bending and torsional strength coupled with a lightweight nature, it is indispensable in manufacturing mechanical parts and engineering structures. Additionally, its versatility extends to common applications in furniture and kitchenware.
Stainless steel pipes come in various types, including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, and more. They also feature bimetal composite pipes and coated pipes, conserving precious metals and fulfilling unique requirements. The diversity in technical specifications and production methods accommodates an extensive range of applications, with steel pipe outer diameters spanning from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm. To delineate their unique properties, stainless steel pipes are systematically classified.

Application requirement
Automobile Industry
In the automotive sector, stainless steel is predominantly utilized in the exhaust system, accounting for over half of the stainless steel used in vehicles. Notably, 80% of this is ferritic stainless steel. The exhaust gases produced by the engine are expelled via a complex system comprising pipes, hoses, converters, and mufflers, primarily using stainless steel welded pipes. It is estimated that automotive applications consume around 1.5% of the total stainless steel pipe demand, with a usage ratio of 2:1 between seamless and welded pipes.
Petrochemical Industry and Fertilizer Sector
The demand for stainless steel pipes in the petrochemical industry is substantial, particularly for seamless types with specifications such as 304, 321, 316, 316L, 347, and 317L. These pipes, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm, are vital for furnace tubes, material conveying tubes, and heat exchanger tubes, especially in medium and low-pressure pipelines.
Water, Gas, and Fluid Transport
Stainless steel pipes, along with their associated water transport equipment, represent the pinnacle of advanced water purification materials. Their superior corrosion resistance sets them apart from cast iron, carbon steel, and plastic pipes, making them the preferred choice for fluid transport.
In the water industry, stainless steel pipes are essential for water preparation, storage, transportation, purification, regeneration, and desalination, with an annual demand of approximately 25,000 tons.
Equipment Manufacturing and Maintenance
This industry sector consumes over 20,000 tons of stainless steel pipes annually, primarily using sanitary or antibacterial grade pipes. Sanitary seamless pipes made from SUS304 and 316L meet the stringent requirements of food and biopharmaceutical media. Antibacterial stainless steel, with its dual advantages of corrosion resistance and antibacterial properties, is increasingly demanded in kitchen equipment, food industry worktables, utensils, medical equipment, and household items like hanging towel brackets and refrigerators.
