Leveraging our extensive experience and culture of continuous improvement, we strive to meet or exceed customer expectations for 2507 stainless steel pipes.
Our forming capabilities stand unparalleled, featuring state-of-the-art extrusion and cold working assets for tube and pipe production. We house one of the world's largest pilger mills and a unique hydroforming process for precision fittings.
As a vertically integrated manufacturer, Daxun provides an all-encompassing, one-stop-shop solution. Whether managing an entire project or handling specific machining tasks, our capabilities include straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
Leveraging cutting-edge vertical and horizontal presses ranging from an impressive 12,000 to a formidable 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. boasts the industry's most expansive and advanced pipe extrusion capabilities. This enables us to craft the longest lengths and the largest diameter stainless steel tubes available, ensuring unparalleled quality and performance.
Daxun Alloys provides high-quality Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. We offer these in various shapes and sizes, all adhering to industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier, we specialize in ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes, delivering excellence from China.
Duplex 2507 stainless steel, a super duplex material with low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%), is designed to meet the stringent demands of applications requiring high strength and exceptional corrosion resistance. Ideal for chemical process equipment, the petrochemical industry, and seawater applications, this steel demonstrates remarkable resistance to chloride-induced stress corrosion cracking. With its high chromium, molybdenum, and nitrogen content, Duplex 2507 offers unparalleled resistance to pitting, crevice corrosion, and other corrosion types.
Daxun Alloy excels in understanding international specifications for super duplex seamless pipes, combining product knowledge with a commitment to supply the best products. Recognized as one of China's premier super duplex pipe suppliers, we stand out due to our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes are integral to the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells aimed at enhancing oil recovery. Known for their superior strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also resist uniform corrosion from organic acids like acetic and formic acids. These pipes offer excellent thermal conductivity and energy absorption. Furthermore, Super Duplex Hollow Pipes are easily machinable and weldable. When heated, pipes identified by number 1.4410 exhibit minimal deformation, preventing faulty flanges or connections. Our 2507 Super Duplex Pipes are essential in heat exchangers for chemical processing, offshore oil and gas operations, and petrochemical manufacturing, adhering to international standards and serving multiple industries globally.
