This unparalleled capability empowers us to produce the longest lengths and the largest diameter pipes available, setting a new benchmark in manufacturing excellence.
Daxun Alloys proudly offers an extensive 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, our products strictly adhere to industry standards such as ASTM, ASME, EURONORM, and AFNOR. As an AS 9100D Certified supplier from China, we specialize in ASTM A790, UNS S32750, and UNS S32760 seamless pipes.
Duplex 2507 stainless steel is renowned for its superior duplex composition, featuring low carbon content (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). Engineered for high-strength and corrosion-resistant applications, this material excels in chemical processing equipment, petrochemical industries, and seawater applications. Its remarkable resistance to chloride-induced stress corrosion cracking, coupled with high chromium, molybdenum, and nitrogen levels, ensures exceptional protection against pitting, crevice corrosion, and other forms of degradation.
Daxun Alloy excels in understanding and meeting international specifications for super duplex seamless pipes. Our competitive pricing, premium quality, and prompt delivery make us one of China's most reliable super duplex pipe suppliers. Trust us for unparalleled product knowledge and service.
Super duplex seamless pipes are indispensable in the oil and gas sector, particularly in high-salinity horizontal wells or brine injection wells aimed at enhancing oil recovery. These pipes are known for their exceptional strength and resistance to corrosion, fatigue, and erosion. ASTM A790 S32750 pipes stand out for their resilience against uniform corrosion from organic acids such as acetic and formic acids. Additionally, these pipes boast superior thermal conductivity and energy absorption, with easy machinability and weldability. The Werkstoff 1.4410 designation indicates minimal deformation under heat, thus preventing defects in flanges or connections. Our 2507 Super Duplex Pipes serve crucial roles in heat exchangers for chemical processing, offshore oil and gas operations, and petrochemical manufacturing, meeting stringent international standards. Our Super Duplex 2507 Seamless Pipes are trusted by industries worldwide.
