As a vertically integrated manufacturer, Daxun offers a comprehensive one-stop solution. From managing entire projects to specific machining jobs, our capabilities include straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
Harnessing the power of vertical and horizontal presses with capacities ranging from an impressive 12,000 to a colossal 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. boasts unrivaled pipe extrusion capabilities in the industry. This extensive range empowers us to produce pipes of unparalleled length and diameter, setting a new standard in manufacturing excellence.
Daxun Alloys proudly offers a comprehensive range of Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. These precision-engineered products meet stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier, we provide ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes, ensuring top-notch quality and reliability for our global clientele.
Duplex 2507 Stainless Steel is a super duplex alloy characterized by its low carbon content (up to 0.03%), enhanced chromium (~25%), nickel (~7%), and molybdenum (~4%) composition. Specifically designed for demanding applications requiring exceptional strength and corrosion resistance, this steel is ideal for chemical process equipment, the petrochemical industry, and seawater applications. Its high chromium, molybdenum, and nitrogen content deliver unparalleled resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
At Daxun Alloy, we possess an in-depth understanding of international specifications for super duplex seamless pipes, ensuring we deliver the right products to our valued customers. Renowned as one of China's top 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, particularly in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. These pipes boast exceptional strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes also resist uniform corrosion from organic acids like acetic and formic acids. Exhibiting excellent thermal conductivity and energy absorption, Super Duplex Hollow Pipes are also easily machinable and weldable. Pipes marked with Werkstoff number 1.4410 show minimal deformation under heat, preventing faulty flanges or connections. Our 2507 Super Duplex Pipes are essential for heat exchangers in chemical processing, offshore oil and gas operations, and petrochemical manufacturing. Fully compliant with international standards, our Super Duplex 2507 Seamless Pipes serve various industries worldwide.
