Application Requirements
Automobile Industry
In the automotive sector, stainless steel is predominantly used in the exhaust system, making up more than half of the stainless steel consumption in vehicles, with 80% being ferritic stainless steel. The exhaust system, comprising components like the muffler, intake pipe, front pipe, hose, converter, and center pipe, typically utilizes steel types such as 409L and 436L. The automotive industry predominantly uses stainless steel welded pipes, which constitute about 1.5% of total downstream stainless steel pipe consumption. The ratio of seamless to welded pipes in this application is approximately 2:1.
Petrochemical and Fertilizer Industry
The petrochemical industry, including the fertilizer sector, has a substantial demand for stainless steel seamless pipes. Common specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thickness varying from 6mm to 50mm. These pipes are specifically utilized in various applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, especially in medium and low-pressure pipelines where diameters exceed 159mm.
Water, Gas, and Fluid Transport
Stainless steel pipes and their associated water transport systems represent the pinnacle of advanced water purification technology today. Their robust corrosion resistance outperforms traditional materials like cast iron, carbon steel, and plastic pipes, making them indispensable in modern fluid transport solutions.
In the water industry, stainless steel pipes are the material of choice for water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for these pipes is approximately 25,000 tons, emphasizing their critical role in maintaining water quality and safety.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually, primarily utilizing sanitary or antibacterial grade pipes. These pipes, made from imported SUS304 and 316L, are designed to meet the stringent requirements of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel offers both durability and excellent antibacterial properties, driving demand in kitchen equipment, food industry worktables, medical devices, daily-use tableware, towel brackets, and refrigeration units.
