This unparalleled capability empowers Daxun to craft the industry's most extensive and robust pipes, ensuring the longest lengths and largest diameters are effortlessly achieved. Trust in Daxun for unmatched pipe extrusion expertise.
Daxun Alloys proudly offers an extensive range of Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. These products come in various shapes and sizes, all meticulously crafted to meet stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier, our offerings include ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes, manufactured with precision and care, directly from China.
Duplex 2507 stainless steel is a super duplex material characterized by its low carbon content (up to 0.03%) and a balanced composition of chromium (approximately 25%), nickel (around 7%), and molybdenum (roughly 4%). This robust alloy is designed to withstand the demanding requirements of high strength and corrosion resistance applications, making it ideal for chemical process equipment, the petrochemical industry, and seawater machinery. Its high chromium, molybdenum, and nitrogen levels ensure exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
At Daxun Alloy, we possess deep expertise in international specifications for super duplex seamless pipes. Our commitment to competitive pricing, superior quality, and timely delivery makes us one of China's leading suppliers of these premium products. We pride ourselves on meeting the diverse needs of our global clientele with unwavering consistency.
Super duplex seamless pipes are highly valued in the oil and gas sector, particularly in high-salinity horizontal wells or brine injection wells aimed at enhancing oil recovery. Known for their remarkable strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also demonstrate strong thermal conductivity and energy absorption. They resist uniform corrosion caused by organic acids like acetic and formic acids, and are easily machinable and weldable. With less deformation when heated (Werkstoff number 1.4410), they ensure reliable flange and connection integrity. Our 2507 Super Duplex Pipes are integral to heat exchangers across chemical processing, offshore oil and gas processing, and petrochemical manufacturing, consistently meeting international standards and serving industries worldwide.
