Our unparalleled capabilities enable us to produce the longest and largest diameter pipes available, setting new standards of excellence.
Daxun Alloys delivers a comprehensive range of Duplex 2507 Stainless Steel Pipes, including 2507 Welded Pipes and 2507 Seamless Pipes, available in various dimensions and conforming to stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. With AS 9100D Certification, we supply ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes, ensuring exceptional quality from China.
Duplex 2507 stainless steel is a high-performance super duplex alloy characterized by its low carbon content (up to 0.03%), along with significant amounts of chromium (~25%), nickel (~7%), and molybdenum (~4%). Designed to excel in demanding applications that require superior strength and corrosion resistance, Duplex 2507 is ideal for chemical process equipment, the petrochemical sector, and seawater systems. Its high chromium, molybdenum, and nitrogen content render it exceptionally resistant to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
At Daxun Alloy, we have an in-depth understanding of international specifications for super duplex seamless pipes. Our extensive product knowledge enables us to supply the precise products our customers need. We are recognized as one of China's leading super duplex pipe suppliers due to our competitive pricing, superior quality, and timely delivery.
Super duplex seamless pipes are crucial in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells that enhance oil recovery. These pipes offer remarkable strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are highly resistant to uniform corrosion from organic acids like acetic and formic acids. Additionally, Super Duplex Stainless Steel Seamless Pipes provide excellent thermal conductivity and energy absorption. Super Duplex Hollow Pipes are also easy to machine and weld. When heated, Werkstoff 1.4410 pipes exhibit minimal deformation, preventing defective flanges or connections. 2507 Super Duplex Pipes are extensively used in heat exchangers for chemical processing, offshore oil and gas, and petrochemical industries. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and are supplied to various industries worldwide.
