Product Description

The stainless steel pipe, a versatile hollow long circular steel, is extensively utilized across various industries, including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its dual bending and torsional strength coupled with lightweight properties make it indispensable in the manufacturing of mechanical components and engineering structures. Additionally, it is frequently used in furniture and kitchenware, showcasing its adaptability and utility.
Stainless steel pipes are categorized into several types: 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. Coatings and coated pipes are also used to conserve precious metals and fulfill specific requirements. With a wide array of diverse uses, technical specifications, and production methods, the outer diameter of steel pipes ranges from 0.1mm to 4500mm, while wall thickness varies from 0.01mm to 250mm. To distinguish their unique characteristics, stainless steel pipes are typically classified using the following method.

Application Requirements
Automobile Industry
In the automotive sector, stainless steel is predominantly used in exhaust systems, which constitute over half of the total stainless steel usage in vehicles, with approximately 80% being ferritic stainless steel. The exhaust gas emitted by the automobile engine is expelled through components such as the muffler, exhaust intake pipe, front pipe, hose, converter, and center pipe. Commonly utilized steel types in exhaust systems include 409L and 436L. Automobile mufflers mainly employ stainless steel welded pipes. It is estimated that the automotive industry accounts for about 1.5% of the total downstream stainless steel pipe consumption, with a usage ratio of stainless steel seamless pipes to welded pipes of about 2:1.
Petrochemical Industry and Fertilizer Sector
The demand for stainless steel pipes is substantial in the petrochemical and fertilizer industries, primarily utilizing stainless steel seamless pipes. Specifications include 304, 321, 316, 316L, 347, 317L, and so on, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Specific applications encompass furnace tubes, material conveying tubes, and heat exchanger tubes.
Water, Gas, and Other Fluid Transport
Stainless steel pipes, alongside their water transport equipment, represent the pinnacle of modern basic water purification materials. Their exceptional corrosion resistance surpasses that of cast iron, carbon steel, and plastic pipes.
In the water industry, encompassing water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes are the premier material choice. The annual demand approximates 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 predominantly uses sanitary or antibacterial grade stainless steel pipes. Made from imported SUS304 and 316L, sanitary seamless pipes cater to the stringent requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel offers excellent antibacterial properties in addition to the inherent benefits of stainless steel. There is increasing demand for these pipes in kitchen equipment, food industry worktables and utensils, medical equipment, daily life tableware, hanging towel brackets, and refrigerators.
