Product Description

Stainless steel pipe, a long, hollow cylindrical steel tube, is extensively utilized across various sectors including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its applications range from industrial transportation pipes to mechanical structural components. Notably, due to its equal bending and torsional strength coupled with light weight, stainless steel pipe is also a preferred material in the production of mechanical parts and engineering structures. Furthermore, it finds common use in the creation of furniture and kitchenware, showcasing its versatility and adaptability.
Stainless steel pipes encompass a variety of 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. They also feature coatings and coated pipes designed to conserve precious metals and fulfill special requirements. The diversity in stainless steel pipes caters to different uses, technical demands, and production methodologies. Currently, these pipes come in an extensive range of outer diameters from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm. To distinguish their unique features, stainless steel pipes are classified according to specific methods.

Application requirement
Automobile Industry
In the automobile sector, stainless steel is predominantly used for exhaust systems, accounting for over half of the total stainless steel consumption in vehicles, with 80% being ferritic stainless steel. The exhaust system, which includes components like the muffler, exhaust gas intake pipe, front pipe, hose, converter, and center pipe, predominantly utilizes steel types such as 409L and 436L. The automotive industry mainly employs stainless steel welded pipes, with the stainless steel pipe consumption by automobiles estimated at about 1.5% of the total downstream stainless steel pipe usage. The ratio of stainless steel seamless pipes to welded pipes in this application is approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The demand for stainless steel pipes in the petrochemical sector is substantial, primarily utilizing stainless steel seamless pipes. Common specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Typically, specifications above Φ159mm are selected for medium and low-pressure pipelines. Key application areas in this industry include furnace tubes, material conveying tubes, and heat exchanger tubes.
Water and Gas Fluid Transport
Stainless steel pipes and their associated water transport equipment represent the pinnacle of advanced basic water purification materials globally. These pipes boast exceptional corrosion resistance, far surpassing that of cast iron, carbon steel, and plastic pipes.
Stainless steel is the material of choice for the water industry, including water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for stainless steel in these applications 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 primarily relies on sanitary or antibacterial grade stainless steel pipes. Made from imported SUS304 and 316L, sanitary seamless pipes meet the stringent requirements of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel, combining the inherent advantages of stainless steel with superior antibacterial properties, is increasingly demanded for kitchen equipment, food industry worktables and utensils, medical equipment, tableware, and daily use items such as hanging towel brackets and refrigerators.
