This exceptional capacity empowers us to manufacture pipes of unparalleled length and diameter, setting a new standard in the industry.
Daxun Alloys proudly offers Duplex 2507 Stainless Steel Pipes, including 2507 Stainless Steel Welded Pipes and 2507 Stainless Steel Seamless Pipes. Our products conform to industry standards like ASTM, ASME, EURONORM, and AFNOR. We are an AS 9100D Certified ASTM A790, UNS S32750, and UNS S32760 Seamless Pipe Supplier from China, dedicated to delivering excellence.
Duplex 2507 stainless steel is a premium super duplex material featuring low carbon (up to 0.03%), chromium (~25%), nickel (~7%), and molybdenum (~4%). It is meticulously designed to meet the stringent demands of applications requiring superior strength and unparalleled corrosion resistance. Ideal for chemical processing equipment, the petrochemical sector, and seawater equipment, this steel excels in resisting chloride-induced stress corrosion cracking. Thanks to its high chromium, molybdenum, and nitrogen content, Duplex 2507 offers outstanding resistance to pitting, crevice corrosion, and other forms of corrosion.
At Daxun Alloy, we are well-versed in the international standards for super duplex seamless pipes. Our expertise enables us to supply products that precisely meet customer requirements. We stand out as one of China's top super duplex pipe suppliers, thanks to our competitive pricing, superior quality, and prompt delivery services.
Super duplex seamless pipes are a cornerstone in the oil and gas industry, as well as in high-salinity horizontal wells or brine injection wells, enhancing oil recovery. Renowned for their exceptional strength and resistance to corrosion, fatigue, and erosion, ASTM A790 S32750 pipes also withstand uniform corrosion from organic acids like acetic and formic acids. These pipes exhibit excellent thermal conductivity and energy absorption capabilities. Additionally, Super Duplex Hollow Pipes are highly machinable and weldable. Pipes marked with Werkstoff number 1.4410 show minimal deformation under heat, crucial for maintaining the integrity of flanges and connections. 2507 Super Duplex Pipes are essential in heat exchangers within chemical processing, offshore oil and gas processing, and petrochemical manufacturing, complying with international standards and serving industries globally.
