Duplex and Super Duplex UNS S32760 Socket Weld Flanges

The Duplex and Super Duplex UNS S32760 Socket Weld Flange (SWF) is a critical forging component widely used in high-pressure, small-bore piping systems (typically NPS 4 and smaller). The design features a recessed socket where the pipe is inserted, creating a superior fit before being secured with an external fillet weld. This connection method is strong, leak-resistant, and easier to align than butt-weld flanges, making it suitable for services where internal fluid erosion is not a major concern. Manufactured from the elite Super Duplex UNS S32760 alloy (also known as F55 or Zeron 100), these flanges benefit from the material's dual-phase microstructure, offering high mechanical strength and outstanding resistance to corrosion. Its high Pitting Resistance Equivalent Number (PREN) provides supreme defense against pitting, crevice corrosion, and stress corrosion cracking (SCC) in aggressive chloride environments. Zeron Fasteners manufactures and supplies these specialized flanges in strict accordance with specifications such as ASME B16.5 and the material standard ASTM A182 F55, ensuring reliable performance in chemical, offshore, and petrochemical facilities.
