This exceptional capability empowers us to manufacture pipes of unparalleled length and the largest diameters available, setting new standards in the industry.
Daxun Alloys offers an extensive range of Duplex 2507 Stainless Steel Pipes, including: 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Available in various shapes and sizes, our products meet industry standards such as ASTM, ASME, EURONORM, and AFNOR. We are AS 9100D Certified and a trusted ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe Supplier from China.
Duplex 2507 stainless steel is a super duplex material characterized by its low carbon content (up to 0.03%), and higher levels of chromium (~25%), nickel (~7%), and molybdenum (~4%). It is designed to meet the stringent requirements of applications requiring high strength and exceptional corrosion resistance, making it ideal for chemical process equipment, the petrochemical industry, and seawater equipment. Its high chromium, molybdenum, and nitrogen content provide outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
Daxun Alloy has extensive knowledge of international standards for super duplex seamless pipes and a proven track record of delivering high-quality products to our clients. We are recognized as one of China's top super duplex pipe suppliers due to our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes are integral to the oil and gas industry and are used in high-salinity horizontal wells or brine injection wells to enhance oil recovery. These pipes are not only highly resistant to corrosion, fatigue, and erosion but also demonstrate excellent thermal conductivity and energy absorption. ASTM A790 S32750 pipes resist uniform corrosion from organic acids such as acetic and formic acids. Additionally, Super Duplex Hollow Pipes are easily machinable and weldable. Werkstoff 1.4410 pipes exhibit minimal deformation when heated, preventing issues with flanges or connections. Our 2507 Super Duplex Stainless Steel Pipes are commonly used in heat exchangers in chemical processing, offshore oil and gas processing, and petrochemical manufacturing, conforming to international standards. We supply Super Duplex 2507 Seamless Pipes to various industries worldwide.
