Application Requirement
Automobile Industry
Stainless steel is predominantly utilized in automobile exhaust systems, representing over half of the total stainless steel used in the automotive sector-with 80% being ferritic stainless steel. The exhaust system, comprising parts like the muffler, intake pipe, front pipe, hose, converter, and center pipe, primarily uses 409L and 436L steel types. Stainless steel welded pipes are the primary choice for mufflers, accounting for about 1.5% of downstream stainless steel pipe consumption. The usage ratio of stainless steel seamless to welded pipes is approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The stainless steel pipe demand in the petrochemical sector is substantial, particularly for seamless pipes in specifications such as 304, 321, 316, 316L, 347, and 317L. These pipes range from 18mm to 610mm in outer diameter and 6mm to 50mm in wall thickness, catering to applications like furnace tubes, material conveying tubes, and heat exchanger tubes. For medium and low-pressure pipelines, specifications typically start from Φ159mm upwards.
Water, Gas, and Other Fluid Transport
Stainless steel pipes and related water transport equipment are the epitome of advanced water purification materials today, boasting unparalleled corrosion resistance. They outperform cast iron, carbon steel, and plastic pipes.
For water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel remains the premier material choice. The annual demand in this sector is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually. This sector predominantly uses sanitary or antibacterial-grade stainless steel pipes made from imported SUS304 and 316L, which meet stringent requirements across various media in food and biopharmaceutical industries. Antibacterial stainless steel is increasingly in demand for kitchen equipment, food industry worktables, utensils, medical equipment, household items, and more, due to its dual advantages of stainless steel properties and antimicrobial features.
