Application Requirement
Automobile Industry Applications
In the automotive industry, stainless steel plays a pivotal role, predominantly in the exhaust system, representing over half of the stainless steel used in vehicles, with 80% being ferritic stainless steel. Exhaust gases from the engine pass through components like the intake pipe, front pipe, hose, converter, and center pipe before exiting via the muffler. Common exhaust system steel types include 409L and 436L, with stainless steel welded pipes being the most prevalent. Stainless steel pipes in the auto sector represent roughly 1.5% of total downstream consumption, with a seamless to welded pipe ratio of 2:1.
Petrochemical and Fertilizer Industry Applications
In the petrochemical sector, the need for stainless steel pipes is significant, mainly utilizing stainless steel seamless pipes. Standard specifications encompass 304, 321, 316, 316L, 347, 317L, etc., with outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are critical in roles 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, along with their complementary water transport equipment, are regarded as the zenith of contemporary water purification materials. Their exceptional corrosion resistance sets them far above cast iron, carbon steel, and plastic pipes.
For processes like water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel is undoubtedly the best material. The annual demand for these pipes stands at about 25,000 tons.
Equipment Manufacturing and Maintenance
With an annual consumption surpassing 20,000 tons, the equipment manufacturing and maintenance industry heavily relies on sanitary or antibacterial grade stainless steel pipes. Crafted from imported SUS304 and 316L, our sanitary seamless pipes satisfy the rigorous demands of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel delivers outstanding durability and antimicrobial properties, making it increasingly favored for kitchen equipment, food industry worktables, medical apparatus, daily tableware, hanging towel racks, and refrigerators.
