Daxun Alloy is dedicated to delivering defect-free products by:
Producing the highest quality and value 2507 stainless steel pipe products. We ensure quick responses and on-time deliveries, prioritize health, safety, and environmental protection, and strictly comply with regulations. With our wealth of experience and commitment to continuous improvement, we strive to meet or exceed customer expectations and requirements for 2507 stainless steel pipes.
Our forming capabilities are unrivaled, featuring advanced extrusion and cold working assets for tube and pipe manufacturing. We boast one of the world's largest pilger mills and a unique hydroforming process for precision fittings, setting the gold standard in the industry.
As a vertically integrated manufacturer, Daxun offers an all-encompassing one-stop-shop solution. Whether managing entire projects or handling specific machining tasks, our capabilities include straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and specialized services.
With an impressive array of vertical and horizontal presses ranging from 12,000 to a staggering 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. boasts the industry's most comprehensive pipe extrusion capabilities. This powerful machinery enables us to produce pipes in the longest lengths and largest diameters available, setting new standards in the industry.
Daxun Alloys offers an extensive range of Duplex 2507 Stainless Steel Pipes, including welded and seamless varieties, meticulously designed to meet stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified Supplier from China, we specialize in ASTM A790, UNS S32750, and UNS S32760 seamless pipes. Our products are crafted to achieve the highest quality and reliability.
Duplex 2507 stainless steel, a super duplex material, features a low carbon content (up to 0.03%) combined with approximately 25% chromium, 7% nickel, and 4% molybdenum. This composition ensures the material meets the demanding requirements of applications needing exceptional strength and corrosion resistance, such as chemical process equipment, petrochemical industries, and seawater equipment. The high levels of chromium, molybdenum, and nitrogen provide superior resistance to pitting, crevice corrosion, and other corrosive conditions, along with excellent protection against chloride-induced stress corrosion cracking.
Daxun Alloy excels in understanding and adhering to international specifications for super duplex seamless pipes. Our in-depth product knowledge allows us to supply high-quality goods tailored to our customers' needs. We are recognized as one of China's premier super duplex pipe suppliers, known for our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes find extensive use in the oil and gas industry, particularly in high-salinity horizontal wells and brine injection wells. Their robustness and exceptional resistance to corrosion, fatigue, and erosion make them ideal for such demanding environments. ASTM A790 S32750 pipes resist uniform corrosion from organic acids like acetic and formic acids, possess strong thermal conductivity, and absorb energy efficiently. Moreover, these pipes are easily machinable and weldable. When heated, Werkstoff number 1.4410 pipes exhibit minimal deformation, crucial for maintaining the integrity of flanges and connections. 2507 Super Duplex Pipes are also integral to heat exchangers in chemical processing, offshore oil, gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and are supplied to various industries globally.
