Duplex 2507 stainless steel is a superior duplex material with low carbon content (up to 0.03%), and significant amounts of chromium (~25%), nickel (~7%), and molybdenum (~4%). Specifically designed to meet the stringent requirements of applications demanding high strength and outstanding corrosion resistance, Duplex 2507 is ideal for chemical process equipment, the petrochemical industry, and seawater applications. Its high resistance to chloride-induced stress corrosion cracking makes it a standout material. The high chromium, molybdenum, and nitrogen content offer unparalleled resistance to pitting, crevice corrosion, and other forms of corrosion.
At Daxun Alloy, we understand the complex international specifications for high-performance super duplex seamless pipes. Our expertise and commitment to quality make us one of China's leading super duplex pipe suppliers, offering competitive pricing, exceptional quality, and timely delivery.
Super duplex seamless pipes are indispensable in the oil and gas industry, especially in high-salinity horizontal wells and brine injection wells to enhance oil recovery. These pipes boast remarkable strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are particularly resilient against uniform corrosion caused by organic acids like acetic and formic acids. These pipes also feature excellent thermal conductivity and energy absorption. Additionally, Super Duplex Hollow Pipes are easy to machine and weld. When heated, pipes marked with Werkstoff number 1.4410 exhibit minimal deformation, reducing the risk of faulty flanges or connections. Our 2507 Super Duplex Pipes are extensively used in heat exchangers within chemical processing, offshore oil and gas processing, and petrochemical manufacturing, and are compliant with international standards. We supply our Super Duplex 2507 Seamless Pipes to various industries worldwide.
