Daxun Alloy pledges to deliver defect-free products to our customers by:
Producing highest-quality 2507 stainless steel pipe products, ensuring rapid responses and timely deliveries, prioritizing health, safety, and environmental protection, and adhering to all legal requirements. We leverage our extensive experience and a culture of continuous improvement to meet or exceed customer expectations and demands for 2507 stainless steel pipes.
Our forming capabilities are unrivaled, featuring advanced extrusion and cold working assets for tube and pipe manufacturing. We host 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 tasks, our capabilities include straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
With state-of-the-art vertical and horizontal presses ranging from 12,000 to an impressive 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. boasts the industry's most comprehensive and advanced pipe extrusion capabilities. This extraordinary capacity empowers us to manufacture the longest and largest diameter stainless steel pipes, setting industry standards in length and diameter.
Daxun Alloys excels in providing a comprehensive range of Duplex 2507 Stainless Steel Pipes including welded and seamless options in various shapes and sizes, meeting stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified supplier, we offer ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes from China, ensuring superior quality and performance.
Duplex 2507 stainless steel stands out as a super duplex material featuring low carbon (up to 0.03%), with chromium (~25%), nickel (~7%), and molybdenum (~4%) composition. It is meticulously designed to meet the demanding requirements of high-strength and high-corrosion resistance applications, including chemical process equipment, petrochemical industries, and seawater equipment. Its exceptional resistance to chloride-induced stress corrosion cracking, due to high chromium, molybdenum, and nitrogen content, offers unparalleled defense against pitting, crevice corrosion, and other forms of degradation.
Jiangsu Daxun Alloy has an in-depth understanding of international specifications for super duplex seamless pipes, combined with extensive product knowledge. We are among China's premier suppliers of super duplex pipes, offering competitive pricing, outstanding quality, and prompt delivery.
Super duplex seamless pipes from Daxun Alloy are prominently used in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells to enhance oil recovery. These pipes exhibit remarkable strength and resistance against corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are notably resistant to uniform corrosion caused by organic acids such as acetic and formic acids. They also boast excellent thermal conductivity and energy absorption. Additionally, our Super Duplex Hollow Pipes are easily machinable and weldable. The 1.4410 Werkstoff pipes, when heated, exhibit minimal deformation, reducing the risk of faulty flanges or connections. 2507 Super Duplex Pipes are essential in heat exchangers used in chemical processing, offshore oil, gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes meet international standards and serve various industries globally.
