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 vertical and horizontal presses boasting a formidable range from 12,000 to an impressive 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. stands at the pinnacle of pipe extrusion capabilities within the industry. This unparalleled range empowers us to fabricate the longest and largest diameter pipes available on the market, setting new standards in manufacturing excellence.
Daxun Alloys offers an extensive selection of Duplex 2507 Stainless Steel Pipes, encompassing welded and seamless variations-each meticulously crafted to adhere to esteemed industry benchmarks including ASTM, ASME, EURONORM, and AFNOR standards. As an AS 9100D Certified ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe Supplier from China, our precision-engineered products stand out in quality and reliability.
Duplex 2507 stainless steel, a super duplex material, is expertly engineered with low carbon (up to 0.03%), high chromium (~25%), nickel (~7%), and molybdenum (~4%) content. Specifically designed for applications necessitating exceptional strength and corrosion resistance, it is ideal for chemical process equipment, the petrochemical sector, and seawater applications. Its formidable resistance to chloride-induced stress corrosion cracking and outstanding defense against pitting, crevice corrosion, and various other corrosive elements attributes to its high chromium, molybdenum, and nitrogen content.
Daxun Alloy is proficient in the international standards governing super duplex seamless pipes, offering unparalleled product expertise to deliver the most suitable solutions for our clients. Our competitive pricing, superior quality, and swift delivery make us one of China's foremost suppliers of super duplex pipes.
Super duplex seamless pipes are pivotal in the oil and gas industry, especially in high-salinity horizontal wells or brine injection wells to enhance oil recovery. Notable for their remarkable strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also withstand uniform corrosion from organic acids such as acetic and formic acids. With exceptional thermal conductivity and energy absorption, these pipes are easily machinable and weldable. Werkstoff number 1.4410 pipes exhibit minimal deformation when heated, thus preventing faulty flanges or connections. Our 2507 Super Duplex Pipes find applications in heat exchangers within chemical processing, offshore oil and gas processing, and petrochemical manufacturing, adhering to rigorous international standards and catering to a global clientele.
