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.
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 unparalleled expertise empowers us to produce pipes with the longest lengths and largest diameters available in the market, setting new standards in the industry.
Daxun Alloys presents an extensive range of Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Our products come in various shapes and sizes adhering to stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. We are an AS 9100D Certified Supplier offering ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes from China.
Duplex 2507 stainless steel stands out as a super duplex material characterized by low carbon (up to 0.03%), high chromium (~25%), nickel (~7%), and molybdenum (~4%) contents. Engineered to satisfy rigorous applications demanding exceptional strength and corrosion resistance, Duplex 2507 is ideally suited for chemical process equipment, the petrochemical industry, and seawater applications. It exhibits remarkable resistance to chloride-induced stress corrosion cracking. Thanks to its high chromium, molybdenum, and nitrogen contents, it provides superior protection against pitting, crevice corrosion, and other forms of corrosion.
At Daxun Alloy, we grasp the intricacies of international specifications for super duplex seamless pipes, ensuring that we deliver products tailored to our clients' needs. Recognized as one of China's premier super duplex pipe suppliers, we pride ourselves on offering competitive pricing, exceptional quality, and prompt delivery.
Super duplex seamless pipes are indispensable in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells aimed at enhancing oil recovery. These super duplex pipes boast superior strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are adept at withstanding uniform corrosion from organic acids such as acetic and formic acids. They also demonstrate strong thermal conductivity and energy absorption. Moreover, Super Duplex Hollow Pipes are readily machinable and weldable. When heated, pipes with Werkstoff number 1.4410 show minimal deformation, essential for maintaining the integrity of flanges and connections. 2507 Super Duplex Pipes prove invaluable across various industries, including heat exchangers in chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes comply with the highest international standards and serve numerous industries worldwide.
