Our stainless steel seamless pipes are a marvel of modern engineering-hollow, long, and circular, designed for unparalleled versatility. Widely adopted in industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation, they are indispensable for industrial transportation and mechanical structural components. Their lightweight yet robust bending and torsional strength make them a staple in the manufacturing of mechanical parts, engineering structures, and even furniture and kitchenware.
Stainless steel pipes are an extensive family, comprising 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 tailored to save precious metals and fulfil special requirements. These versatile pipes come in a vast array of types, uses, technical specifications, and production methods. Currently, our steel pipe outer diameters range from 0.1mm to 4500mm, with wall thicknesses spanning 0.01mm to 250mm. For clarity, we classify these pipes based on their distinct characteristics.

Application Requirement
Automobile Industry Applications
In the automotive sector, stainless steel is primarily utilized in the exhaust system, accounting for over half of the stainless steel used in vehicles, with 80% being ferritic stainless steel. Exhaust gases from the engine travel through components like the intake pipe, front pipe, hose, converter, and center pipe, exiting via the muffler. Commonly used steel types in exhaust systems include 409L and 436L, with stainless steel welded pipes being predominant. Stainless steel pipes in the auto industry represent about 1.5% of total downstream consumption, with a 2:1 ratio of seamless to welded pipes.
Petrochemical and Fertilizer Industry Applications
In the petrochemical industry, the demand for stainless steel pipes is substantial, primarily using stainless steel seamless pipes. Specifications include 304, 321, 316, 316L, 347, 317L, etc., with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are vital in applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, particularly in medium and low-pressure pipelines with diameters above 159mm.
Water and Gas Fluid Transport
Stainless steel pipes and their accompanying water transport equipment are considered the pinnacle of modern water purification materials. Their superior corrosion resistance makes them far superior to cast iron, carbon steel, and plastic pipes.
For activities like water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel remains the best material. The annual demand for these pipes is about 25,000 tons.
Equipment Manufacturing and Maintenance
With an annual consumption exceeding 20,000 tons, the equipment manufacturing and maintenance industry primarily relies on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, crafted from imported SUS304 and 316L, meet the stringent requirements of various media in food and biopharmaceutical fields. Antibacterial stainless steel offers excellent durability and antibacterial properties, making it increasingly popular for kitchen equipment, food industry worktables, medical equipment, daily tableware, hanging towel brackets, and refrigerators.
