Application Requirements
Automotive Industry Innovations
In the automotive sector, stainless steel is primarily used in exhaust systems, comprising over half of the total stainless steel usage in automobiles, with 80% being ferritic stainless steel. The exhaust system, made from types like 409L and 436L, includes components such as the intake pipe, front pipe, hose, converter, and center pipe, and uses mainly stainless steel welded pipes. Approximately 1.5% of all downstream stainless steel pipe consumption is dedicated to automotive applications, with a usage ratio of about 2:1 for seamless to welded pipes.
Petrochemical Industry and Fertilizer Sector
The demand for stainless steel pipes in the petrochemical industry is substantial, particularly for seamless pipes. Specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are primarily used in furnace tubes, material conveyance tubes, and heat exchanger tubes, especially for medium and low-pressure pipelines above Φ159mm.
Water, Gas, and Fluid Transport Innovations
Stainless steel pipes and their associated water transport equipment are among the most advanced materials for global water purification. Their superior corrosion resistance outshines that of cast iron, carbon steel, and plastic pipes, positioning them as the top choice for water-related applications.
For water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes are the optimal material. The annual demand for these high-grade pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
Annually, over 20,000 tons of stainless steel pipes are consumed in the equipment manufacturing and maintenance industry. This sector predominantly uses sanitary or antibacterial grade stainless steel pipes. Imported SUS304 and 316L sanitary seamless pipes meet the stringent requirements of food and biopharmaceutical applications. The demand for antibacterial stainless steel, due to its dual benefits of durability and antimicrobial protection, is rising in kitchen equipment, food industry worktables, medical equipment, daily-use tableware, hanging towel brackets, and refrigerator components.
