Application Requirement
Automobile Industry Applications
In the dynamic automotive sector, stainless steel plays a crucial role, predominantly in the exhaust system, making up over half of the stainless steel used in vehicles, with the vast majority being ferritic stainless steel. Engine exhaust gases traverse through components such as the intake pipe, front pipe, hose, converter, and center pipe, ultimately exiting via the muffler. The exhaust system commonly employs steel types such as 409L and 436L, with stainless steel welded pipes being the norm. In the automotive industry, stainless steel pipes constitute about 1.5% of the total downstream consumption, maintaining a 2:1 ratio of seamless to welded pipes.
Petrochemical and Fertilizer Industry Applications
In the expansive petrochemical industry, the demand for stainless steel pipes is substantial, with a focus on stainless steel seamless pipes. Key specifications include 304, 321, 316, 316L, 347, 317L, etc., featuring outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are critical for applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, particularly in medium and low-pressure pipelines with diameters exceeding 159mm.
Water and Gas Fluid Transport
Stainless steel pipes, alongside their corresponding water transport equipment, represent the pinnacle of modern water purification materials. Their superior corrosion resistance sets them leagues apart from cast iron, carbon steel, and plastic pipes, making them the premier choice for longevity and reliability.
For activities encompassing water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel stands as the material of choice. The annual demand for these pipes hovers around 25,000 tons, underscoring their critical importance and widespread adoption.
Equipment Manufacturing and Maintenance
With an annual consumption surpassing 20,000 tons, the equipment manufacturing and maintenance industry heavily relies on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, fashioned from imported SUS304 and 316L, meet the rigorous standards of various media in the food and biopharmaceutical fields. Antibacterial stainless steel, with its outstanding durability and antibacterial properties, is gaining traction for kitchen equipment, food industry worktables, medical equipment, daily tableware, hanging towel brackets, and refrigerators.
