Application Requirement
Automobile Industry
In the automotive industry, stainless steel is predominantly utilized in exhaust systems, comprising over half of the total stainless steel used in vehicles, with 80% being ferritic stainless steel. Exhaust system components such as the muffler, exhaust gas intake pipe, front pipe, hose, converter, and center pipe primarily use steel types like 409L and 436L. The automotive sector mainly employs stainless steel welded pipes, with stainless steel pipe consumption by automobiles estimated at about 1.5% of the total downstream usage. The ratio of stainless steel seamless pipes to welded pipes in this application is approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The petrochemical sector's demand for stainless steel pipes is substantial, primarily utilizing seamless varieties. Common specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Pipes above Φ159mm are typically chosen for medium and low-pressure pipelines. Key application areas include furnace tubes, material conveying tubes, and heat exchanger tubes.
Water and Gas Fluid Transport
Stainless steel pipes and their associated water transport equipment represent the pinnacle of advanced basic water purification materials globally. These pipes exhibit exceptional corrosion resistance, greatly surpassing that of cast iron, carbon steel, and plastic pipes.
Stainless steel stands as the material of choice for the water industry, encompassing water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for stainless steel in these applications is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance sector consumes over 20,000 tons of stainless steel pipes annually. This industry predominantly relies on sanitary or antibacterial grade stainless steel pipes. Made from imported SUS304 and 316L, sanitary seamless pipes meet the stringent requirements of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel, merging the advantages of stainless steel with superior antibacterial properties, is increasingly in demand for kitchen equipment, food industry worktables and utensils, medical equipment, tableware, and daily-use items such as hanging towel brackets and refrigerators.
