Construction, Welding & Application The slip on flange (S/O flange) manufactured in accordance with ASME B16.5 is a loose-type flange which has no direct connection to the adjoining pipe wall or the nozzle neck, or the vessel. It has a low hub that allows the flange to slip onto the pipe prior to welding. Two fillet welds, one internal and …

Design and Construction The welding neck flange (WN) conforming to ASME B16.5 is a typical integral-type flange. It is cast or forged integrally with the tapered neck which is butt welded to the pipe. This design provides a smooth transition with little stress concentration since the high-stress concentration at the base of the flange is reduced by transferring stress to …
