At Jiangsu Daxun Alloy Co., Ltd., we pride ourselves on an unparalleled range of pipe extrusion capabilities. Our state-of-the-art facilities feature impressive vertical and horizontal presses, boasting capacities from 12,000 to 35,000 tons. This substantial range allows us to craft pipes of remarkable lengths and diameters, consistently setting industry benchmarks in both size and quality.
Jiangsu Daxun Alloy Co., Ltd. shines in the realm of Duplex 2507 Stainless Steel Pipes, including both welded and seamless varieties. Our diverse product range meets rigorous industry standards such as ASTM, ASME, EURONORM, and AFNOR, reflecting our commitment to excellence. As an AS 9100D Certified supplier, we offer ASTM A790, UNS S32750, and UNS S32760 seamless pipes directly from China, ensuring unmatched quality and reliability in every delivery.
Duplex 2507 stainless steel, renowned as a super duplex material, features a remarkable composition with low carbon (up to 0.03%), chromium (approximately 25%), nickel (about 7%), and molybdenum (around 4%). Crafted for high-strength, corrosion-resistant applications, this alloy is ideal for chemical process equipment, petrochemical industries, and seawater systems. The high levels of chromium, molybdenum, and nitrogen deliver outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
With profound expertise in global specifications for super duplex seamless pipes, Daxun Alloy is adept at supplying impeccably tailored products. We have established ourselves as one of China's premier super duplex pipe suppliers through our competitive pricing, exceptional quality, and timely delivery.
Super duplex seamless pipes are vital in the oil and gas sector, especially in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Renowned for their strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also resist uniform corrosion from organic acids like acetic and formic acids. These pipes offer excellent thermal conductivity and energy absorption, making them incredibly durable. With superior machinability and weldability, Werkstoff 1.4410 pipes experience minimal deformation under heating, ensuring reliable flanges and connections. Our 2507 Super Duplex Pipes are extensively utilized in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing, adhering to international standards and serving industries worldwide.
