Application requirement
Automobile Industry
In the automobile sector, stainless steel is predominantly utilized for exhaust systems, contributing to over half of the total stainless steel consumption in vehicles, with 80% being ferritic stainless steel. Components like mufflers, exhaust gas intake pipes, front pipes, hoses, converters, and center pipes typically use steel types such as 409L and 436L. The automotive industry 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 demand for stainless steel pipes in the petrochemical sector is substantial, primarily utilizing stainless steel seamless pipes. 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. Typically, specifications above Φ159mm are selected 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 associated water transport equipment represent the pinnacle of advanced basic water purification materials globally. Boasting exceptional corrosion resistance, their performance far surpasses that of cast iron, carbon steel, and plastic pipes.
Stainless steel is the material of choice for the water industry, including 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 primarily relies on sanitary or antibacterial grade stainless steel pipes. Made from imported SUS304 and 316L, sanitary seamless pipes meet stringent requirements of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel, combining inherent stainless steel advantages with superior antibacterial properties, is increasingly demanded for kitchen equipment, food industry worktables and utensils, medical equipment, tableware, and daily use items such as hanging towel brackets and refrigerators.
