Stainless steel pipes are a type of hollow, long circular steel widely used across numerous industries, including petroleum, chemical, medical, food, light industry, mechanical instrumentation, and various industrial transportation pipes and mechanical structural components. Due to their equal bending and torsional strength with a lightweight nature, they are also prevalent in the manufacturing of mechanical parts and engineering structures. Additionally, these pipes are commonly utilized in furniture and kitchenware.
Stainless steel pipes are categorized into different types, such as ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, and bimetal composite pipes. These variations help in saving precious metals and meeting unique requirements. Multiple kinds of stainless steel pipes exist, each with distinct uses, technical specifications, and production methods. Current production capabilities include outer diameters ranging from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm. To distinguish their characteristics, stainless steel pipes are classified using the following methodologies.

Application Requirements
Automobile Industry Applications
Stainless steel plays a major role in the automobile industry, particularly in exhaust systems, which use over half of the stainless steel employed in vehicles, with 80% being ferritic stainless steel. The exhaust gases produced by the automobile engine travel through various components such as the exhaust gas intake pipe, front pipe, hose, converter, and center pipe before being discharged from the muffler. Commonly used steel types in exhaust systems include 409L and 436L. Automobile mufflers predominantly utilize stainless steel welded pipes. Approximately 1.5% of the entire downstream stainless steel pipe consumption is attributed to automobiles, with a use ratio of stainless steel seamless pipes to welded pipes being about 2:1.
Petrochemical Industry Applications, Including the Fertilizer Industry
The petrochemical industry has a substantial demand for stainless steel pipes, primarily using seamless variants. Common specifications include 304, 321, 316, 316L, 347, 317L, with outer diameters around 18-¢610mm and wall thicknesses ranging from 6mm to 50mm. Typically, specifications above Φ159mm are selected for medium and low-pressure pipelines. Specific applications include furnace tubes, material conveying tubes, and heat exchanger tubes.
Water, Gas, and Other Fluid Transport Applications
Stainless steel pipes, along with their associated water transport equipment, represent the most advanced basic water purification materials in the world today. Their exceptional corrosion resistance surpasses that of cast iron, carbon steel, and plastic pipes.
For water preparation, storage, transportation, purification, regeneration, and desalination in the water industry, stainless steel pipes are the best material choice. The annual demand for these pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance Applications
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually. This sector predominantly uses sanitary or antibacterial grade stainless steel pipes. Sanitary seamless pipes made from imported SUS304 and 316L meet the special requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel offers both the benefits of stainless steel and superior antibacterial properties, with increasing demand in kitchen equipment, food industry worktables, utensils, medical equipment, tableware, daily life accessories, refrigerators, and other fields.
