Zeron Fastners
Duplex and Super Duplex UNS S32205 Socket Weld Flanges
The Duplex and Super Duplex UNS S32205 Socket Weld Flange (SW Flange) is primarily used for small-bore, high-pressure piping systems (typically NPS 4 or less). The pipe end is inserted into the flange's socket and then secured with a single fillet weld around the outside. This design provides high structural integrity and is favored for its ease of installation, as it requires no precise alignment or beveling of the pipe end before welding. Zeron Fasteners manufactures these from UNS S32205 (Duplex 2205), ensuring excellent mechanical strength and superior corrosion resistance against harsh environments, making them ideal for non-critical, high-pressure service in chemical plants and hydraulic systems where leak prevention is paramount.
