Whether managing entire projects or handling specific machining jobs, our capabilities encompass straightening, drilling, honing, trepanning, cutting, testing, boring, machining, laser welding, polishing, turning, and various specialized services.
Equipped with vertical and horizontal presses ranging from an impressive 12,000 to a staggering 35,000 tons, Jiangsu Daxun Alloy Co., Ltd. boasts the industry's most comprehensive pipe extrusion capabilities. This unparalleled technology empowers us to produce the longest lengths and largest diameter pipes available, setting new standards in the industry.
Daxun Alloys proudly offers Duplex 2507 Stainless Steel Pipes - including welded and seamless variants. Our products come in a myriad of shapes and sizes, all adhering to stringent industry standards like ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified supplier, we specialize in ASTM A790, UNS S32750, and UNS S32760 seamless pipes, delivering quality and precision from China to the world.
Duplex 2507 stainless steel is a premium super duplex alloy featuring low carbon (up to 0.03%), and enriched with chromium (~25%), nickel (~7%), and molybdenum (~4%). It's engineered to fulfill the stringent demands of applications requiring exceptional strength and corrosion resistance. Ideal for chemical process equipment, petrochemical sectors, and seawater systems, this steel excels in resisting chloride-induced stress corrosion cracking. Its high chromium, molybdenum, and nitrogen composition ensures unparalleled resistance to pitting, crevice corrosion, and other forms of degradation.
Daxun Alloy is renowned for comprehending and meeting international standards for super duplex seamless pipes. Our expertise and product knowledge empower us to deliver optimal solutions to our global clientele. As one of China's premier super duplex pipe suppliers, we take pride in our competitive pricing, superior quality, and on-time delivery.
Super duplex seamless pipes find extensive use in the oil and gas industry, particularly in high-salinity horizontal wells or brine injection wells to enhance oil recovery. These pipes are known for their exceptional strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes withstand uniform corrosion caused by organic acids like acetic and formic acids, exhibit excellent thermal conductivity, and are highly energy efficient. Moreover, Super Duplex Hollow Pipes are easily machinable and weldable. Pipes marked Werkstoff number 1.4410 show minimal deformation upon heating, crucial for maintaining flange and connection integrity. 2507 Super Duplex Pipes are indispensable in heat exchangers for chemical processing, offshore oil and gas operations, and petrochemical manufacturing. Our Super Duplex 2507 Seamless Pipes meet international standards and are trusted by various industries worldwide.
