Application Requirement
Automobile Industry Applications
Within the automotive sector, stainless steel plays a pivotal role, predominantly in exhaust systems, which account for over half of the stainless steel utilized in vehicles. An impressive 80% is ferritic stainless steel. Exhaust gases journey through components like the intake pipe, front pipe, hose, converter, and center pipe, culminating at the muffler. Preferred steel types in exhaust systems are 409L and 436L, with stainless steel welded pipes leading the choice. In the auto industry, stainless steel pipes make up about 1.5% of total downstream consumption, with a preference ratio of 2:1 for seamless over welded pipes.
Petrochemical and Fertilizer Industry Applications
In the petrochemical industry, the need for stainless steel pipes is significant, with a clear preference for stainless steel seamless pipes. Specifications include 304, 321, 316, 316L, 347, 317L, and more, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are crucial for applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, especially in medium and low-pressure pipelines with diameters above 159mm.
Water and Gas Fluid Transport
Stainless steel pipes, along with their water transport equipment, are heralded as the apex of modern water purification materials. Their exceptional corrosion resistance sets them leagues ahead of alternatives like cast iron, carbon steel, and plastic pipes.
For processes such as water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel emerges as the material of choice. The annual demand for these indispensable pipes stands at approximately 25,000 tons.
Equipment Manufacturing and Maintenance
With an impressive annual consumption exceeding 20,000 tons, the equipment manufacturing and maintenance sector heavily relies on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, fashioned from imported SUS304 and 316L, adhere to the stringent standards required in the food and biopharmaceutical industries. Antibacterial stainless steel is celebrated for its outstanding durability and antibacterial properties, gaining popularity in kitchen equipment, food industry worktables, medical equipment, everyday tableware, hanging towel brackets, and refrigerators.
