Our cutting-edge technology enables us to produce pipes of unparalleled lengths and diameters, setting new benchmarks in manufacturing excellence.
Daxun Alloys proudly offers Duplex 2507 Stainless Steel Pipes - 2507 Stainless Steel Welded Pipes - 2507 Stainless Steel Seamless Pipes, available in a wide variety of shapes and sizes that conform to industry standards including ASTM, ASME, EURONORM, and AFNOR. Our AS 9100D Certified offerings include ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes, all sourced from China.
Duplex 2507 stainless steel is an extraordinary super duplex material characterized by its low carbon content (up to 0.03%), as well as substantial amounts of chromium (~25%), nickel (~7%), and molybdenum (~4%). This high-performance alloy is specifically designed to endure the stringent demands of high-strength and high-corrosion resistance applications. Essential sectors such as chemical processing, petrochemical industry, and seawater equipment rely on this material due to its impressive resistance to chloride-induced stress corrosion cracking. Enhanced by high levels of chromium, molybdenum, and nitrogen, Duplex 2507 offers unmatched resistance to pitting, crevice corrosion, and various other forms of corrosion.
At Daxun Alloy, we possess a deep understanding of international specifications for super duplex seamless pipes, empowering us to deliver the ideal products to our clients with precision. Renowned as one of China's premier super duplex pipe suppliers, we stand out for our competitive pricing, superior quality, and prompt delivery services.
Super duplex seamless pipes play a crucial role in the oil and gas industry, especially in environments characterized by high salinity, such as horizontal wells and brine injection wells aimed at enhancing oil recovery. Apart from their formidable strength, these pipes are highly resistant to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are also resilient against uniform corrosion caused by organic acids like acetic and formic acids. Distinguished by strong thermal conductivity and superior energy absorption, Super Duplex Stainless Steel Seamless Pipes are both easily machinable and weldable. When heated, Werkstoff pipes marked with 1.4410 exhibit minimal deformation, reducing the risk of faulty flanges or connections. The 2507 Super Duplex Pipes are instrumental in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes meet international standards and are delivered to various industries globally.
