Socket Weld Flanges / SWRF Flanges

Socket Weld Flanges are used only for high pressure and temperature applications upto diameters of 1 ½” only. This creates a smooth bore with the proper welding and grinding. Socket Welding Flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings.
