Stainless steel pipe is a type of hollow, long circular steel, extensively utilized across diverse industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its lightweight nature, combined with equal bending and torsional strength, makes it indispensable in manufacturing mechanical parts and engineering structures. Furthermore, it finds significant applications in furniture and kitchenware, showcasing its versatility and robustness.
Stainless steel pipes are categorized into various types, including 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. These classifications ensure the conservation of precious metals and fulfill unique requirements. Stainless steel pipes come in a multitude of forms, each tailored for specific uses, technical standards, and production processes. The current production specifications range from an outer diameter of 0.1-4500mm to a wall thickness of 0.01~250mm. For clarity, steel pipes are classified based on these distinctive characteristics.

Application Requirement
Automobile Industry
In the automobile industry, stainless steel is predominantly used in exhaust systems, constituting over half of the total stainless steel used in vehicles, with 80% being ferritic stainless steel. The exhaust system, which channels emissions from the engine through various components such as the muffler and converter, predominantly utilizes steel types like 409L and 436L. Notably, stainless steel welded pipes are the primary material for automobile mufflers. It is estimated that automotive applications account for approximately 1.5% of the total downstream consumption of stainless steel pipes, with a usage ratio of seamless to welded pipes being about 2:1.
Petrochemical Industry and Fertilizer Sector
The demand for stainless steel pipes in the petrochemical industry is substantial, with a preference for seamless variants. Common specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18-¢610mm and wall thicknesses between 6mm and 50mm. Typical applications encompass furnace tubes, material conveying tubes, and heat exchanger tubes, especially for medium and low-pressure pipelines above Φ159mm.
Water, Gas, and Fluid Transport
Stainless steel pipes and related water transport equipment represent the pinnacle of modern water purification materials, boasting unparalleled corrosion resistance. No other materials such as cast iron, carbon steel, or plastic pipes can match their performance.
In the water industry, stainless steel is the superior choice for processes including preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for these pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance sector consumes over 20,000 tons of stainless steel pipes annually. This industry predominantly utilizes sanitary or antibacterial grade pipes. High-quality seamless pipes made from imported SUS304 and 316L meet the stringent requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel combines excellent stainless properties with robust antibacterial capabilities, increasingly in demand for kitchen equipment, food industry worktables, utensils, medical apparatus, daily use tableware, towel brackets, and refrigerators.
