Boasting an impressive range of vertical and horizontal presses from 12,000 to 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. stands at the pinnacle of pipe extrusion technology. Our unparalleled capabilities enable us to produce pipes in the longest lengths and largest diameters the industry has ever seen, meeting even the most demanding specifications with precision and excellence.
Daxun Alloys provides Duplex 2507 Stainless Steel Pipes - offering 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Our products come in various shapes and sizes, meeting top-tier industry standards like ASTM, ASME, EURONORM, and AFNOR. We are AS 9100D Certified ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe suppliers from China.
Duplex 2507 stainless steel is a super duplex material, featuring low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%) content. It is designed to meet the stringent demands of applications requiring high strength and superior corrosion resistance. This includes equipment in chemical processing, the petrochemical sector, and seawater machinery. Duplex 2507 stainless steel is highly resistant to chloride-induced stress corrosion cracking and offers outstanding resistance to pitting, crevice corrosion, and various other forms of degradation due to its high chromium, molybdenum, and nitrogen content.
Daxun Alloy comprehends international specifications for super duplex seamless pipes, ensuring we supply appropriate, high-quality products to our clients. Recognized as one of China's finest super duplex pipe suppliers, we pride ourselves on competitive pricing, exceptional quality, and timely delivery.
Super duplex seamless pipes are extensively used in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. They boast superior strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes are also resilient against uniform corrosion from organic acids such as acetic and formic acids. These pipes exhibit strong thermal conductivity and energy absorption. Moreover, Super Duplex Hollow Pipes are highly machinable and weldable. Werkstoff 1.4410 pipes maintain their shape under heat, reducing the risk of deformed flanges or connections. 2507 Super Duplex Pipes find applications in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes conform to international standards and are supplied to various industries across the globe.
