Our unparalleled capabilities empower us to craft the longest, most expansive diameter pipes seen in the market, ensuring unmatched quality and reliability.
At Daxun Alloys, we specialize in providing superior Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Available in a variety of shapes and sizes, our products adhere to stringent industry standards such as ASTM, ASME, EURONORM, and AFNOR. We are proudly AS 9100D Certified and offer ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe, making us a trusted supplier from China.
Duplex 2507 stainless steel is a super duplex material characterized by its low carbon content (up to 0.03%), and high chromium (~25%), nickel (~7%), and molybdenum (~4%) content. It is engineered to meet the demanding requirements of applications needing unparalleled strength and corrosion resistance. Ideal for chemical process equipment, the petrochemical industry, and seawater applications, it boasts remarkable resistance to chloride-induced stress corrosion cracking. Thanks to its elevated levels of chromium, molybdenum, and nitrogen, it excels in resisting pitting, crevice corrosion, and various other corrosion types.
Daxun Alloy is acutely aware of the international specifications for super duplex seamless pipes, and we possess the requisite product knowledge to deliver precisely what our customers need. Distinguished as one of China's premier super duplex pipe suppliers, we are known for our competitive pricing, superior quality, and prompt delivery.
Super duplex seamless pipes are pivotal in the oil and gas industry, especially in high-salinity horizontal wells and brine injection wells for enhanced oil recovery. These pipes are renowned for their exceptional strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes stand resilient against uniform corrosion caused by organic acids such as acetic and formic acids. Additionally, these super duplex stainless steel seamless pipes showcase impressive thermal conductivity and energy absorption. They are also easily machinable and weldable. When heated, Werkstoff 1.4410 pipes deform minimally, reducing the risk of faulty flanges or connections. 2507 Super Duplex Pipes are integral in heat exchangers for chemical processing, offshore oil and gas processing, and petrochemical manufacturing. Our 2507 Super Duplex Stainless Steel Pipes adhere to international standards and are supplied to numerous industries worldwide.
