ASME/ANSI B16.5 600 Class Socket Welding Flange/Standards, Dimensions & Weight

The SW forged flange shares similarities with slip-on and socket welding flanges, but has a counter-bored bore that can accommodate pipes. The remaining diameter of the bore matches the inside diameter of the pipe. A fillet weld is used to attach the Socket Welding Flange to the pipe’s hub, while an additional internal weld may be necessary for high-stress applications. Socket Flanges are widely used in high-pressure systems like hydraulic and steam lines.
