Stainless steel pipes are premium hollow long circular steel tubes, predominantly utilized across various industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Their lightweight yet strong bending and torsional capabilities make them indispensable in the construction of mechanical parts and engineering structures. Additionally, they find extensive application in household items like furniture and kitchenware.
Stainless steel pipes encompass a diverse range including ordinary carbon steel, high-quality carbon structural steel, alloy structural steel, bearing steel, bimetal composite, and coated pipes. Each type serves distinct purposes, adheres to unique technical specifications, and is manufactured through varied processes. The diameter of these pipes spans from 0.1mm to 4500mm, with wall thicknesses ranging from 0.01mm to 250mm. Classification is generally based on specific characteristics and intended applications.

Application Requirements
Automobile Industry
Stainless steel is primarily utilized in automotive exhaust systems, representing over half of the total stainless steel used in vehicles. Ferritic stainless steel, such as types 409L and 436L, is prevalent. The exhaust gases from the engine pass through various components like the intake pipe, muffler, and converter, made from stainless steel welded pipes. Automotive applications constitute about 1.5% of the total stainless steel pipe consumption, with a usage ratio of seamless to welded pipes at roughly 2:1.
Petrochemical Industry, Including Fertilizer Industry
The petrochemical sector demands high volumes of stainless steel seamless pipes. Specifications include grades like 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Main applications are furnace tubes, material conveying tubes, and heat exchanger tubes, especially in medium and low-pressure pipelines above Φ159mm.
Water, Gas, and Other Fluid Transport
Stainless steel pipes and their associated equipment represent the pinnacle of advanced water purification materials globally. Their unparalleled corrosion resistance sets them apart from cast iron, carbon steel, and plastic pipes.
For water industry applications such as preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes are the optimal choice. The annual demand for these pipes is around 25,000 tons.
Equipment Manufacturing and Maintenance
The annual consumption of stainless steel pipes in this sector exceeds 20,000 tons. Industries here predominantly use sanitary or antibacterial-grade stainless steel pipes. Seamless pipes made from imported SUS304 and 316L meet stringent requirements for various media within the food and biopharmaceutical fields. Antibacterial stainless steel combines excellent hygiene properties with robust stainless steel benefits, driving demand in kitchen equipment, food industry worktables, medical equipment, and everyday items like tableware and towel brackets.
