At Jiangsu Daxun Alloy Co., Ltd., we are devoted to delivering defect-free products by:
Producing the highest quality and most valuable 2507 stainless steel pipe products, ensuring quick responses and on-time deliveries. We prioritize health, safety, and environmental protection, strictly adhering to laws. Leveraging our experience and culture of continuous improvement, we aim to consistently meet or exceed customer expectations and requirements for 2507 stainless steel pipes.
Our forming capabilities are unparalleled, featuring advanced extrusion and cold working assets for tube and pipe manufacturing. We proudly host one of the world's largest pilger mills and a unique hydroforming process for precision fittings.
As a vertically integrated manufacturer, Jiangsu Daxun Alloy Co., Ltd. provides a comprehensive one-stop-shop solution. Whether managing an entire project or handling specific machining jobs, our capabilities encompass straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
At Jiangsu Daxun Alloy Co., Ltd., our state-of-the-art vertical and horizontal presses, ranging from 12,000 to an impressive 35,000 tons, position us as leaders in pipe extrusion capabilities. This unparalleled capacity enables us to produce pipes of extraordinary lengths and diameters, setting industry standards for excellence.
Daxun Alloys offers an extensive range of Duplex 2507 Stainless Steel Pipes, including welded and seamless variants, in various shapes and sizes. These pipes adhere to industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier from China, we provide ASTM A790, UNS S32750, and UNS S32760 seamless pipes that meet the highest standards of quality and performance.
Duplex 2507 stainless steel is a superior duplex material, characterized by low carbon (up to 0.03%), high chromium (~25%), nickel (~7%), and molybdenum (~4%) content. Designed for demanding applications requiring high strength and exceptional corrosion resistance, Duplex 2507 is ideal for chemical process equipment, petrochemical industries, and seawater equipment. Its high chromium, molybdenum, and nitrogen content provide outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
At Daxun Alloy, we excel in meeting international specifications for super duplex seamless pipes, backed by our deep product knowledge. Our competitive pricing, superior quality, and prompt delivery make us one of China's premier super duplex pipe suppliers.
Super duplex seamless pipes play a critical role in the oil and gas industry, particularly in high-salinity horizontal wells and brine injection wells to enhance oil recovery. These pipes boast remarkable strength, corrosion resistance, and resistance to fatigue and erosion. ASTM A790 S32750 pipes also withstand uniform corrosion from organic acids like acetic and formic acids. They exhibit strong thermal conductivity and energy absorption. Furthermore, Super Duplex Hollow Pipes are easily machinable and weldable, demonstrating minimal deformation when heated (1.4410 Werkstoff Number). These pipes are essential in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes meet international standards and are supplied to diverse industries globally.
