Application Requirement
Automobile Industry Applications
In the automotive industry, stainless steel is predominantly harnessed in the exhaust system, representing more than half of the stainless steel utilized in vehicles, of which 80% is ferritic stainless steel. Exhaust gases journey through components like the intake pipe, front pipe, hose, converter, and center pipe, finally exiting through the muffler. Commonly employed steel types include 409L and 436L, with stainless steel welded pipes taking precedence. Stainless steel pipes in the automotive domain constitute approximately 1.5% of total downstream consumption, with a 2:1 ratio favoring seamless pipes over welded pipes.
Petrochemical and Fertilizer Industry Applications
In the petrochemical sector, the demand for stainless steel pipes is notably high, with an emphasis on stainless steel seamless pipes. Specifications frequently used include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses between 6mm and 50mm. These pipes play an essential role in applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, especially in medium and low-pressure pipelines with diameters exceeding 159mm.
Water and Gas Fluid Transport
Stainless steel pipes, along with their associated water transport equipment, are hailed as the apex of contemporary water purification materials. Their unparalleled corrosion resistance renders them superior to cast iron, carbon steel, and plastic pipes.
For operations like water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel is unrivaled. The annual demand for these pipes approximates 25,000 tons.
Equipment Manufacturing and Maintenance
With an annual consumption surpassing 20,000 tons, the equipment manufacturing and maintenance realm heavily depends on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, crafted from imported SUS304 and 316L, adhere to the rigorous standards of various media within the food and biopharmaceutical industries. Antibacterial stainless steel affords excellent durability and antibacterial traits, gaining popularity for kitchen equipment, food industry worktables, medical devices, daily tableware, towel brackets, and refrigerators.
