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.
Equipped with state-of-the-art vertical and horizontal presses ranging from an impressive 12,000 to a colossal 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. stands at the forefront of the pipe extrusion industry. Our unparalleled capabilities enable us to produce the longest lengths and largest diameter pipes, setting new standards in the market.
Daxun Alloys presents a superior range of Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Available in various shapes and sizes, these pipes adhere to industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe Supplier from China, we guarantee excellence in every product.
Duplex 2507 stainless steel stands out as a super duplex material with a meticulously balanced composition of low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). Engineered to meet the exacting demands of applications requiring supreme strength and corrosion resistance, this steel is ideal for chemical process equipment, the petrochemical industry, and seawater systems. Renowned for its robust resistance to chloride-induced stress corrosion cracking, its high chromium, molybdenum, and nitrogen content confer exceptional resistance to pitting, crevice corrosion, and other forms of corrosion.
At Daxun Alloy, we excel in understanding and meeting international specifications for super duplex seamless pipes. Our dedication to competitive pricing, superior quality, and punctual delivery has established us as one of China's premier super duplex pipe suppliers.
The oil and gas industry, along with high-salinity horizontal wells and brine injection wells, rely on the extraordinary strength and corrosion resistance of super duplex seamless pipes to enhance oil recovery. ASTM A790 S32750 pipes resist uniform corrosion from organic acids like acetic and formic acids. These pipes also boast high thermal conductivity and energy absorption, making them ideal for various demanding applications. Our 2507 Super Duplex Stainless Steel Pipes, compliant with international standards, are widely used in chemical processing, offshore oil and gas processing, and petrochemical manufacturing, ensuring reliability and performance across industries.
