Leveraging our extensive experience and culture of continuous improvement, we strive to meet or exceed customer expectations and requirements for 2507 stainless steel pipes.
Our forming capabilities are unmatched, featuring advanced extrusion and cold working assets for tube and pipe manufacturing. We possess one of the world's largest pilger mills and a unique hydroforming process for precision fittings.
As a vertically integrated manufacturer, Daxun offers a comprehensive one-stop-shop solution. Whether managing an entire project or handling specific machining jobs, our capabilities include straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
Equipped with state-of-the-art vertical and horizontal presses that range from an impressive 12,000 to 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. leads the industry with unparalleled pipe extrusion capabilities. This exceptional machinery enables us to produce pipes of extraordinary lengths and diameters, setting new benchmarks in the market.
Daxun Alloys proudly offers an extensive range of Duplex 2507 Stainless Steel Pipes, including Welded and Seamless varieties. These pipes come in numerous shapes and sizes, all adhering to stringent industry standards like ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier, we provide ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes directly from our state-of-the-art facilities in China.
Duplex 2507 stainless steel is a superior, super duplex material characterized by its low carbon content (up to 0.03%) and enriched with high levels of chromium (~25%), nickel (~7%), and molybdenum (~4%). It is specifically designed to meet the demanding requirements of applications that necessitate exceptional strength and outstanding corrosion resistance. Ideal for use in chemical processing equipment, the petrochemical sector, and seawater applications, this steel excels in resisting chloride-induced stress corrosion cracking. Thanks to its robust composition, including high chromium, molybdenum, and nitrogen, it offers unparalleled resistance to pitting, crevice corrosion, and other types of corrosion.
Daxun Alloy is acutely aware of the exacting international specifications for super duplex seamless pipes. Our in-depth product knowledge enables us to supply the most suitable products to our clientele. We stand out as one of China's premier super duplex pipe suppliers, known for our competitive pricing, superior quality, and on-time delivery.
Super duplex seamless pipes are indispensable in the oil and gas industry and are frequently employed in high-salinity horizontal wells and brine injection wells to enhance oil recovery. These pipes are also highly durable, offering exceptional resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are particularly resistant to uniform corrosion from organic acids such as acetic and formic acids. Notably, ASTM A790 Super Duplex Stainless Steel Seamless Pipes boast superior thermal conductivity and energy absorption. Super Duplex Hollow Pipes are also straightforward to machine and weld. Notably, Werkstoff pipes labeled 1.4410 exhibit minimal deformation when heated, which minimizes the risk of faulty flanges or connections. Our 2507 Super Duplex Pipes are essential in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. We pride ourselves on delivering 2507 Super Duplex Stainless Steel Pipes that meet rigorous international standards to diverse industries globally.
