Duplex 2507 stainless steel is a superior duplex material with a precise composition of low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). Engineered to fulfill the stringent demands of applications necessitating high strength and exceptional corrosion resistance, it is ideal for chemical process equipment, the petrochemical industry, and seawater machinery. Its robust resistance to chloride-induced stress corrosion cracking, coupled with high chromium, molybdenum, and nitrogen levels, ensures outstanding defense against pitting, crevice corrosion, and various other corrosion forms.
Daxun Alloy excels in understanding international specifications for super duplex seamless pipes, leveraging our in-depth product knowledge to supply precise solutions to our clients. Our competitive pricing, unmatched quality, and prompt delivery make us one of China's premier super duplex pipe suppliers.
Super duplex seamless pipes are indispensable in the oil and gas sector and are extensively utilized in naturally high-salinity horizontal wells or brine injection wells to enhance oil recovery. Renowned for their exceptional strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also withstand uniform corrosion caused by organic acids like acetic and formic acids. These pipes exhibit superior thermal conductivity and energy absorption, and their machinability and weldability are excellent. Notably, Werkstoff 1.4410 pipes demonstrate minimal deformation when heated, ensuring integrity in flanges or connections. 2507 Super Duplex Pipes are widely adopted in heat exchangers for chemical processing, offshore oil and gas operations, and petrochemical production. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards, serving a multitude of industries globally.
