Product Description

Revolutionize your industry applications with our premium stainless steel pipe. This versatile hollow cylindrical steel is celebrated across diverse fields such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its robust strength in both bending and torsion, combined with its lightweight nature, makes it the optimal choice for crafting intricate mechanical parts, sophisticated engineering structures, and even the most elegant furniture kitchenware.
Explore the diverse world of stainless steel compositions with our expertly crafted series: the Cr series (400 series), the Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series), and the advanced precipitation hardening series (600 series).
200 series: This series features an innovative blend of chromium, manganese, and nickel.
201,202, etc.: In these grades, manganese replaces nickel, offering a cost-effective alternative with moderate corrosion resistance, used extensively in China as an economical substitute for the premium 300 series.
300 series: Featuring chromium-nickel austenitic stainless steel, this series stands out for its superior qualities.
304: A versatile general model known as 18/8 stainless steel, ideal for corrosion-resistant containers, tableware, furniture, railings, and medical equipment. Comprising 18% chromium and 8% nickel, it remains non-magnetic and its metallographic structure stays unchanged by heat treatment. It meets the GB grade 06Cr19Ni10 standards.
304 L: With the same remarkable characteristics as 304, this version has lower carbon content, enhancing corrosion resistance and making it easily heat-treatable, though with slightly reduced mechanical properties. Perfect for welding and applications where heat treatment is challenging.
304 N: Sharing the robust features of 304, this nitrogen-enhanced stainless steel boasts increased strength due to its nitrogen content.
309: Specifically designed for superior temperature resistance, enduring heat up to 980°C.
309 S: This variant is laden with chromium and nickel, providing excellent heat and oxidation resistance. Ideal for applications like heat exchangers, boiler components, and jet engines.
310: Renowned for its exceptional high-temperature oxidation resistance, withstanding operational temperatures up to 1200°C.
316: Following 304, 316 is a highly sought-after steel grade for the food industry, watch accessories, pharmaceuticals, and surgical equipment. Enhanced with molybdenum, it offers superior chloride corrosion resistance, earning its title as 'marine steel.' SS316 is frequently used in nuclear fuel recovery systems, aligning with 18/10 grade stainless steel for high-level applications.
316 L: With reduced carbon content, this variant offers heightened corrosion resistance and ease of heat treatment. Suitable for applications such as chemical processing equipment, nuclear power generators, and refrigerant storage tanks.
410: A martensitic steel with high-strength chromium, offering commendable wear resistance but limited corrosion resistance.
420: Known as 'tool-grade' martensitic steel, akin to Brinell high-chromium steel, it was one of the earliest stainless steels. It is also favored for crafting surgical knives that can achieve exceptional brightness.

Petrochemical and Fertilizer Industry
The petrochemical industry demands top-grade stainless steel pipes, with a strong preference for seamless varieties. Common specifications encompass 304, 321, 316, 316L, 347, and 317L, with outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are vital in numerous applications like furnace tubes, material conveying tubes, and heat exchanger tubes, particularly for medium and low-pressure pipelines.
Water and Gas Fluid Transport
Stainless steel pipes are the pinnacle of excellence in fluid transport systems, boasting unparalleled corrosion resistance that outshines the likes of cast iron, carbon steel, and plastic pipes. This superior quality positions these pipes, along with their associated equipment, as some of the most elite water purification materials available on a global scale.
Stainless steel pipes stand as the quintessential materials for the water industry, seamlessly integrating into processes such as water preparation, storage, transportation, purification, regeneration, and desalination. The market appetite for these crucial pipes reaches an impressive demand of approximately 25,000 tons annually.
Equipment Manufacturing and Maintenance
The equipment manufacturing industry relies heavily on stainless steel pipes, with an annual consumption surpassing 20,000 tons, especially in sanitary or antibacterial grades. Crafted mainly from SUS304 and 316L grades, these pipes adhere to the rigorous standards demanded by diverse media across the food and biopharmaceutical sectors. Antibacterial stainless steel, revered for its fusion of durability and antimicrobial prowess, is increasingly sought after in the production of kitchen equipment, worktables for the food industry, medical instruments, and even household staples like towel brackets and refrigerators.
