Product Description

Our 304 Stainless Steel Pipe with a mirror surface finish is a versatile, hollow, circular steel product prized for its extensive applications across numerous industries. It is predominantly used in the petroleum, chemical, medical, food, light industry, and mechanical instrumentation sectors for transporting fluids and gases. Furthermore, its impressive bending and torsional strength, combined with its lightweight nature, make it an ideal choice for manufacturing mechanical parts and engineering structures. Its aesthetic appeal also makes it a popular choice for furniture and kitchenware.
Stainless steel pipes are categorized into several types, including ordinary carbon steel, high-quality carbon structural steel, alloy structural, alloy steel, bearing steel, and bimetal composite pipes. Additionally, there are coated pipes that save precious metals and meet specialized requirements. Each type serves different purposes and has unique technical specifications and production methods. Our product range includes steel pipes with outer diameters from 0.1 to 4500mm and wall thickness ranging from 0.01 to 250mm. Stainless steel pipes are typically classified based on these characteristics and their intended applications.

Application Requirement
Automobile Industry
In the automobile industry, stainless steel is primarily used in exhaust systems, constituting over half of the total stainless steel used in vehicles, with 80% being ferritic stainless steel. The exhaust system comprises components like the intake pipe, front pipe, hose, converter, and center pipe, which guide exhaust gases from the engine to the muffler. Steel types 409L and 436L are commonly used. Stainless steel welded pipes are the mainstay for automotive mufflers, with the automotive sector consuming about 1.5% of the total stainless steel pipe market, favoring a 2:1 ratio of seamless to welded pipes.
Petrochemical Industry, including the Fertilizer Sector
The petrochemical and fertilizer industries exhibit a robust demand for stainless steel pipes, predominantly utilizing seamless types. Specifications include 304, 321, 316, 316L, 347, and 317L, covering outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are essential for applications like furnace tubes, material conveying tubes, and heat exchanger tubes, particularly in medium and low-pressure pipelines above 159mm.
Water, Gas, and Fluid Transport
Stainless steel pipes and their associated water transport equipment represent the pinnacle of modern water purification materials, boasting unmatched corrosion resistance compared to cast iron, carbon steel, and plastic pipes.
For water preparation, storage, transport, purification, regeneration, and desalination, stainless steel is the material of choice, with an annual demand of approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance sector consumes over 20,000 tons of stainless steel pipes annually, primarily opting for sanitary or antibacterial grade types. Pipes made from imported SUS304 and 316L meet stringent requirements in the food and biopharmaceutical industries. Antibacterial stainless steel, known for its excellent hygienic properties, is increasingly used in kitchen equipment, food industry worktables, medical devices, and everyday items like tableware, towel brackets, and refrigerators.
