Application requirement
Automobile Industry
In the automobile industry, stainless steel is extensively used, particularly in exhaust systems, which account for over half of the total stainless steel consumption in vehicles, with 80% being ferritic stainless steel. Key components include the muffler, exhaust gas intake pipe, front pipe, hose, converter, and center pipe, predominantly utilizing steel types such as 409L and 436L. The industry mainly employs stainless steel welded pipes, with around 1.5% of the total stainless steel pipe usage attributable to the automotive sector. The ratio of stainless steel seamless pipes to welded pipes in this context is approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The petrochemical and fertilizer industries have a substantial demand for stainless steel pipes, 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. Specifications above Φ159mm are typically used for medium and low-pressure pipelines. Key applications in these industries 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 worldwide. These pipes offer exceptional corrosion resistance, far exceeding that of cast iron, carbon steel, and plastic pipes.
Stainless steel is the premier material for the water industry, encompassing 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 sector primarily relies on sanitary or antibacterial grade stainless steel pipes, made from imported SUS304 and 316L. Sanitary seamless pipes meet stringent requirements for 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.
