Our stainless steel seamless pipes represent a pinnacle of cutting-edge engineering-characterized by their hollow, elongated, and circular design, which offers unmatched versatility. These pipes are widely embraced across multiple sectors, including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. They are essential for industrial transportation as well as for the creation of mechanical structural components. Their lightweight nature combined with extraordinary bending and torsional strength makes them indispensable in the fabrication of mechanical parts, engineering structures, and even in the construction of furniture and kitchenware.
Stainless steel pipes form a broad and comprehensive family, including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, bimetal composite pipes, and coated pipes-all meticulously crafted to conserve precious metals while meeting specialized demands. These adaptable pipes are available in a wide spectrum of types, applications, technical specifications, and manufacturing processes. At present, our steel pipes boast external diameters ranging from an incredibly fine 0.1mm to a robust 4500mm, with wall thicknesses extending from a delicate 0.01mm to a substantial 250mm. For ease of reference, we categorize these pipes according to their unique characteristics.

Application Requirement
Automobile Industry Applications
In the automotive industry, stainless steel plays a significant role, particularly in exhaust systems, which use more than half of a vehicle's stainless steel, with 80% being ferritic stainless steel. Exhaust gases from the engine pass through vital components such as the intake pipe, front pipe, hose, converter, and center pipe before exiting through the muffler. Predominantly used steel types for exhaust systems include 409L and 436L, with stainless steel welded pipes being the primary choice. In the automotive sector, stainless steel pipes constitute about 1.5% of the overall downstream consumption, maintaining a 2:1 ratio of seamless to welded pipes.
Petrochemical and Fertilizer Industry Applications
Within the petrochemical industry, there is a substantial requirement for stainless steel pipes, particularly stainless steel seamless pipes. Available in specifications like 304, 321, 316, 316L, 347, 317L, etc., these pipes have outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are crucial in applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, especially within medium and low-pressure pipelines where diameters exceed 159mm.
Water and Gas Fluid Transport
Stainless steel pipes, along with their water transport equipment counterparts, are considered the ultimate choice for contemporary water purification solutions. Their extraordinary corrosion resistance renders them far superior to cast iron, carbon steel, and plastic pipes.
For operations like water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel stands as the unrivaled material of choice. The demand for these pipes annually is around 25,000 tons.
Equipment Manufacturing and Maintenance
In the equipment manufacturing and maintenance sector, with an annual consumption surpassing 20,000 tons, the industry primarily relies on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, crafted from imported SUS304 and 316L, adhere to the rigorous standards required for various media in the food and biopharmaceutical fields. Antibacterial stainless steel offers remarkable durability and antibacterial properties, making it increasingly favored for kitchen equipment, food industry worktables, medical equipment, everyday tableware, hanging towel brackets, and refrigerators.
