A Global Leader in Stainless Steel Pipe and Tube Fabrication Services
Daxun Alloys offers a superior range of Duplex 2507 Stainless Steel Pipes, including Welded and Seamless options, crafted to meet stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. Our AS 9100D Certified Seamless Pipes, including ASTM A790, UNS S32750, and UNS S32760, position us as a top supplier from China.
Duplex 2507 stainless steel is a super duplex material characterized by low carbon content (up to 0.03%) and rich in chromium (~25%), nickel (~7%), and molybdenum (~4%). Designed to meet rigorous application demands for high strength and exceptional corrosion resistance, it is ideal for chemical process equipment, petrochemical industries, and seawater applications. This alloy is highly resistant to chloride-induced stress corrosion cracking and offers outstanding resistance to pitting, crevice corrosion, and other forms of corrosion due to its high chromium, molybdenum, and nitrogen content.
Daxun Alloy excels in understanding international specifications for super duplex seamless pipes, leveraging our extensive product knowledge to deliver the best solutions to our customers. We are a leading super duplex pipe supplier in China, known for our competitive pricing, superior quality, and reliable delivery.
Super duplex seamless pipes are essential in the oil and gas industry and are used in high-salinity horizontal wells or brine injection wells to enhance oil recovery. These pipes offer remarkable strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes resist uniform corrosion caused by organic acids like acetic and formic acids and exhibit excellent thermal conductivity and energy absorption. Additionally, Super Duplex Hollow Pipes are easily machinable and weldable. With less deformation under heat, pipes with Werkstoff Number 1.4410 are less prone to faulty flanges or connections, making them ideal for chemical processing heat exchangers, offshore oil and gas processing, and petrochemical manufacturing. Our Super Duplex 2507 Seamless Pipes comply with international standards and are supplied to various industries worldwide.
