Application Requirement
Automobile Industry Applications
In the dynamic realm of 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, with a notable 80% being ferritic stainless steel. As exhaust gases journey from the engine, they traverse components such as the intake pipe, front pipe, hose, converter, and center pipe, culminating their journey via the muffler. The preferred steel types for exhaust systems include 409L and 436L, with stainless steel welded pipes being predominantly favored. In the auto industry, stainless steel pipes constitute approximately 1.5% of total downstream consumption, maintaining a 2:1 ratio of seamless to welded pipes.
Petrochemical and Fertilizer Industry Applications
Within the expansive petrochemical industry, the demand for stainless steel pipes is both substantial and unwavering, primarily leveraging stainless steel seamless pipes. Specifications such as 304, 321, 316, 316L, 347, and 317L are at the forefront, with outer diameters ranging from 18mm to 610mm, and wall thicknesses extending from 6mm to 50mm. These pipes are indispensable for applications including 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, along with their advanced water transport equipment, represent the zenith of modern water purification materials. Their exceptional corrosion resistance positions them far ahead of traditional materials like cast iron, carbon steel, and plastic pipes.
For critical activities involving water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel emerges as the material of choice. The annual demand for these superior pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry, with an annual consumption surpassing 20,000 tons, relies heavily on sanitary or antibacterial grade stainless steel pipes. Our sanitary seamless pipes, meticulously crafted from imported SUS304 and 316L, are designed to meet the rigorous requirements of diverse media in the food and biopharmaceutical sectors.
