Application requirement
Automobile Industry
In the automotive domain, stainless steel is predominantly employed for exhaust systems, accounting for over 50% of the total stainless steel usage in vehicles, with an impressive 80% being ferritic stainless steel. The exhaust system parts, including the muffler, exhaust gas intake pipe, front pipe, hose, converter, and center pipe, primarily use steel types such as 409L and 436L. The industry relies heavily on stainless steel welded pipes, with their consumption in automobiles estimated at around 1.5% of the total downstream stainless steel pipe usage. The ratio of stainless steel seamless pipes to welded pipes stands at approximately 2:1 in this application.
Petrochemical Industry and Fertilizer Industry
Demand for stainless steel pipes in the petrochemical sector is significant, primarily involving 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. Typically, specifications above Φ159mm are selected for medium and low-pressure pipelines. Key applications in this industry 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 water purification materials globally. These pipes offer superior corrosion resistance, far exceeding that of cast iron, carbon steel, and plastic pipes.
Stainless steel is the material of choice 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 devours over 20,000 tons of stainless steel pipes annually. This industry primarily relies on sanitary or antibacterial grade stainless steel pipes. Made from imported SUS304 and 316L, these sanitary seamless pipes meet the rigorous standards required by the food and biopharmaceutical sectors. Antibacterial stainless steel, combining the inherent benefits of stainless steel with superior antibacterial properties, is increasingly in demand for kitchen equipment, food industry worktables and utensils, medical equipment, tableware, and daily items like hanging towel brackets and refrigerators.
