Application Requirement
Automobile Industry Applications
In the automotive industry, the strategic use of stainless steel is revolutionizing vehicle performance, with its primary application in the exhaust system. This use accounts for over half of the stainless steel employed in automobiles, with an impressive 80% being ferritic stainless steel. As exhaust gases journey from the engine, they traverse various components including the intake pipe, front pipe, hose, converter, and center pipe, finally exiting through the muffler. The commonly utilized steel types in exhaust systems are 409L and 436L, with stainless steel welded pipes being most prevalent. In the automotive domain, stainless steel pipes account for approximately 1.5% of total downstream consumption, maintaining a seamless to welded pipes ratio of 2:1.
Petrochemical and Fertilizer Industry Applications
In the dynamic realm of the petrochemical industry, stainless steel pipes are in high demand, predominantly in the form of stainless steel seamless pipes. Key specifications include 304, 321, 316, 316L, 347, 317L, and more, with outer diameters ranging from 18mm to a substantial 610mm, and wall thicknesses from 6mm to 50mm. These pipes play a crucial role in applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, particularly in medium and low-pressure pipelines with diameters exceeding 159mm.
Water and Gas Fluid Transport
Stainless steel pipes, alongside their accompanying water transport equipment, represent the pinnacle of modern water purification materials. Their exceptional corrosion resistance places them leagues ahead of cast iron, carbon steel, and plastic pipes.
For critical activities such as water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel remains the unrivaled material of choice. Annually, the demand for these superior pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry leans heavily on sanitary or antibacterial grade stainless steel pipes, with annual consumption surpassing 20,000 tons. Our sanitary seamless pipes, crafted from high-quality imported SUS304 and 316L, fulfill the stringent requirements of various media in the food and biopharmaceutical fields.
