Flange Socket Weld Raised Face (SWRF)

An SWRF (Slip-On Weld Neck Raised Face) flange combines features of both slip-on and weld neck flanges. It has a slip-on design, allowing it to slide over the pipe before being welded in place, and a raised face for improved sealing. Unlike standard slip-on flanges, the SWRF flange has a neck that provides additional strength and alignment. The raised face enhances the gasket seal, making it suitable for applications requiring a more robust connection, often found in high-pressure and high-temperature systems.
