Product Description

Stainless steel pipe is a versatile and essential hollow, long circular steel, predominantly used across a myriad of industries including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its unique attributes, such as equal bending and torsional strength combined with lightweight properties, make it ideal for manufacturing mechanical parts and engineering structures. Furthermore, it finds extensive application in furniture and kitchenware, attributing to its robustness and aesthetic appeal.
Stainless steel pipes encompass a wide spectrum of categories: from ordinary carbon steel pipes and high-quality carbon structural steel pipes to alloy structural pipes, bearing steel pipes, and bimetal composite pipes. To economize precious metals and meet specialized demands, coatings and coated pipes are also fabricated. The diversity in usage, technical requirements, and production methods lead to a vast range of stainless steel pipes. Current production sees outer diameters ranging from 0.1mm to 4500mm and wall thickness from 0.01mm to 250mm. This variety necessitates precise classification to distinguish their unique properties.

Application requirement
Automobile industry
Stainless steel's paramount application within the automobile industry is the exhaust system, which consumes over half of the stainless steel used in cars, with 80% being ferritic stainless steel. The automobile exhaust system comprises the exhaust gas intake pipe, front pipe, hose, converter, and center pipe, primarily using types 409L and 436L stainless steel. Estimates suggest that automotive applications account for approximately 1.5% of total downstream stainless steel pipe consumption, with a 2:1 ratio of seamless to welded stainless steel pipes.
Petrochemical industry, including the fertilizer sector
The petrochemical industry exhibits a significant demand for stainless steel pipes, particularly seamless variants. Typical specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to ¢610mm and wall thicknesses from 6mm to 50mm. Applications span across furnace tubes, material conveying tubes, and heat exchanger tubes, particularly favoring dimensions above Φ159mm for medium and low-pressure pipelines.
Water, gas, and other fluid transport
Stainless steel pipes represent the pinnacle of advanced water purification materials, with exceptional corrosion resistance surpassing that of cast iron, carbon steel, and plastic pipes. Their superior properties make them the material of choice for modern water transport equipment.
Ideal for water industry applications such as preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes witness an annual demand of around 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 predominantly utilizes sanitary or antibacterial grade stainless steel pipes. Sanitary seamless pipes made from imported SUS304 and 316L meet stringent requirements for various media in the food and biopharmaceutical industries. Additionally, antibacterial stainless steel offers exceptional stainless properties and superior antibacterial performance, driving demand in kitchen equipment, food industry worktables, medical equipment, tableware, and everyday appliances like towel brackets and refrigerators.
