Stainless steel pipe, known for its hollow and elongated circular structure, stands as a versatile material extensively utilized across numerous industries. These include petroleum, chemical, medical, food, light industry, and mechanical instrumentation sectors, where it serves vital roles in industrial transportation and mechanical structural components. Notably, its equal bending and torsional strength combined with a lightweight nature makes it indispensable in the fabrication of mechanical parts and engineering structures. Furthermore, it finds common applications in furniture and kitchenware manufacturing.
Stainless steel pipes can be categorized into various types: ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes. Additionally, coated and plated pipes are available to conserve precious metals and meet specialized requirements. The diversity in stainless steel pipes is reflected in their varied uses, technical specifications, and production methods. Presently, the production spectrum encompasses outer diameters ranging from 0.1mm to 4500mm and wall thicknesses between 0.01mm to 250mm. For better identification and application, stainless steel pipes are classified according to specific features and characteristics.

Application Requirements
Automobile Industry Applications
In the automotive sector, stainless steel is predominantly utilized in exhaust systems, comprising over half of the stainless steel used in vehicles, with 80% being ferritic stainless steel. The exhaust gases from the automobile engine are expelled through a series of components including the muffler, intake pipe, front pipe, hose, converter, and center pipe. Common steel types for these applications are 409L and 436L. Stainless steel welded pipes are primarily used for mufflers. On average, stainless steel pipes make up about 1.5% of the total downstream consumption, with a usage ratio of stainless steel seamless pipes to welded pipes standing at 2:1.
Petrochemical Industry and Fertilizer Sector
The petrochemical industry, notably the fertilizer sector, demonstrates a significant demand for stainless steel pipes, primarily employing stainless steel seamless pipes. Key specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Typical applications encompass furnace tubes, material conveying tubes, and heat exchanger tubes, especially in pipelines over Φ159mm for medium to low-pressure systems.
Water, Gas, and Fluid Transport
Stainless steel pipes, along with their water transport equipment, stand as the pinnacle of advanced water purification materials globally. Their superior corrosion resistance far exceeds that of cast iron, carbon steel, and plastic pipes, positioning them as unmatched contenders in the fluid transport sector.
In the water industry, including preparation, storage, transportation, purification, regeneration, and desalination processes, stainless steel pipes are the material of choice. The annual demand for these high-performance pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually. This sector primarily utilizes sanitary or antibacterial grade stainless steel pipes. The use of imported SUS304 and 316L sanitary seamless pipes ensures they meet the stringent requirements of various media in food and biopharmaceutical fields. Antibacterial stainless steel pipes combine the robust characteristics of stainless steel with advanced antibacterial properties, increasingly demanded in kitchen equipment, food industry worktables, utensils, medical equipment, tableware, and household items such as towel brackets and refrigerators.
