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.
Boasting an impressive array of vertical and horizontal presses ranging from a formidable 12,000 to a colossal 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. stands at the forefront of the pipe extrusion industry. Our expansive capabilities enable us to produce the longest and largest diameter pipes available, setting new standards for excellence and innovation.
Daxun Alloys provides a comprehensive range of Duplex 2507 Stainless Steel Pipes, including welded and seamless variations. Available in various shapes and sizes, our pipes meet stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. Proudly AS 9100D Certified, we are a leading supplier of ASTM A790, UNS S32750, and UNS S32760 Seamless Pipes in China.
Duplex 2507 stainless steel is a super duplex material renowned for its low carbon content (up to 0.03%) and exceptional blend of chromium (~25%), nickel (~7%), and molybdenum (~4%). Engineered for applications requiring outstanding strength and corrosion resistance, it is ideal for the chemical process equipment, petrochemical industry, and seawater equipment. Its high chromium, molybdenum, and nitrogen content provide unparalleled resistance to chloride-induced stress corrosion cracking, pitting, and various other forms of corrosion.
Daxun Alloy excels in understanding and adhering to international specifications for super duplex seamless pipes. Our competitive pricing, superior quality, and prompt delivery make us one of China's premier super duplex pipe suppliers.
Super duplex seamless pipes are indispensable in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Known for their exceptional strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also resist uniform corrosion caused by organic acids such as acetic and formic acids. These pipes exhibit impressive thermal conductivity and energy absorption, and they are easily machinable and weldable. The 1.4410 Werkstoff number pipes demonstrate minimal deformation upon heating, crucial for maintaining the integrity of flanges and connections. Utilized in chemical processing heat exchangers, offshore oil and gas processing, and petrochemical manufacturing, our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and serve industries worldwide.
