Application requirement
Automobile Industry
In the automotive sector, stainless steel is predominantly used for exhaust systems, accounting for over half of the total stainless steel consumption in vehicles, with 80% being ferritic stainless steel. The exhaust system, which includes components like the muffler, exhaust gas intake pipe, front pipe, hose, converter, and center pipe, predominantly utilizes steel types such as 409L and 436L. The automotive industry primarily employs stainless steel welded pipes, with the stainless steel pipe consumption by automobiles estimated at about 1.5% of the total downstream stainless steel pipe usage. The ratio of stainless steel seamless pipes to welded pipes in this application is approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The demand for stainless steel pipes in the petrochemical sector is substantial, 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. Typically, specifications above Φ159mm are selected for medium and low-pressure pipelines. Key application areas 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 basic water purification materials globally. These pipes boast exceptional corrosion resistance, far surpassing 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 consumes 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, sanitary seamless pipes meet the stringent requirements of 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.
