Application Requirement
Automobile Industry
In the automobile sector, stainless steel is predominantly utilized for exhaust systems, making up over half of the total stainless steel used in vehicles, with 80% being ferritic stainless steel. The exhaust system components, such as mufflers, exhaust gas intake pipes, front pipes, hoses, converters, and center pipes, primarily use steel types like 409L and 436L. The automotive industry mainly employs stainless steel welded pipes, with the consumption of stainless steel pipes 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 petrochemical industry has a substantial demand for stainless steel pipes, primarily using 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 sector 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 in the water industry for applications including water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for stainless steel in these sectors 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.
