As a vertically integrated manufacturer, Daxun offers an all-encompassing one-stop-shop solution. Whether it's 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.
At Jiangsu Daxun Alloy Co., Ltd., we pride ourselves on an unparalleled array of pipe extrusion capabilities. Our advanced vertical and horizontal presses, ranging from 12,000 to a colossal 35,000 tons, enable us to manufacture pipes of extraordinary lengths and diameters. This vast capacity sets new industry benchmarks for both size and quality, redefining excellence in pipe production.
Daxun Alloys stands at the forefront of the stainless steel pipe industry, specializing in the creation of Duplex 2507 Stainless Steel Pipes. Our extensive range includes both 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Available in diverse shapes and sizes, each product rigorously adheres to esteemed industry standards such as ASTM, ASME, EURONORM, and AFNOR. As a trusted AS 9100D Certified supplier, we deliver premium ASTMA790, UNS S32750, and UNS S32760 seamless pipes from China, guaranteeing unparalleled quality and reliability.
Duplex 2507 stainless steel, a remarkable super duplex material, features a low carbon content (up to 0.03%), along with approximately 25% chromium, 7% nickel, and 4% molybdenum. This precision-engineered alloy is designed to endure the rigorous demands of high-strength, corrosion-resistant applications, making it ideal for chemical process equipment, the petrochemical sector, and seawater systems. Its rich composition of chromium, molybdenum, and nitrogen provides extraordinary resistance against pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
With profound expertise in international specifications for super duplex seamless pipes, Daxun Alloy ensures the perfect match for our clients' needs. We are recognized as one of China's leading super duplex pipe suppliers, thanks to our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes are indispensable in the oil and gas industry, especially in high-salinity horizontal wells or brine injection wells for enhanced oil recovery. Renowned for their exceptional strength and unparalleled resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also exhibit resilience against uniform corrosion from organic acids such as acetic and formic acids. These pipes offer excellent thermal conductivity and energy absorption, ensuring remarkable durability. Additionally, Werkstoff 1.4410 pipes feature excellent machinability and weldability, experiencing minimal deformation under heating, thus providing reliable flanges and connections. Our 2507 Super Duplex Pipes are extensively used in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing, complying with international standards and serving industries globally.
