Our state-of-the-art pipe extrusion technology ensures unparalleled options for every application, setting new standards in the industry.
Daxun Alloys offers a premium selection of Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Available in a broad range of shapes and sizes, our products adhere to stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. We are AS 9100D Certified and provide ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes directly from China.
Duplex 2507 stainless steel is a super duplex material characterized by low carbon content (up to 0.03%), high chromium (~25%), nickel (~7%), and molybdenum (~4%) levels. Engineered to meet the demanding requirements of high-strength and corrosion-resistant applications, this steel is ideal for use in chemical process equipment, the petrochemical industry, and seawater applications. It offers outstanding resistance to chloride-induced stress corrosion cracking, as well as superior protection against pitting, crevice corrosion, and other forms of corrosion due to its high chromium, molybdenum, and nitrogen content.
At Daxun Alloy, we excel in understanding the global standards for super duplex seamless pipes, ensuring we deliver the right products to our customers. Renowned as one of China's premier super duplex pipe suppliers, we pride ourselves on competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes are indispensable in the oil and gas sector, especially in high-salinity horizontal wells and brine injection wells to enhance oil recovery. They are robust, corrosion-resistant, and resilient against fatigue and erosion. ASTM A790 S32750 pipes withstand uniform corrosion from organic acids like acetic and formic acids. These pipes also boast high thermal conductivity and energy absorption. Super Duplex Hollow Pipes are easily machinable and weldable. When heated, pipes marked with Werkstoff number 1.4410 show minimal deformation, preventing faulty flanges or connections. Applications of 2507 Super Duplex Pipes span heat exchangers in chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes comply with international standards, serving various industries globally.
