Abstract
1303240 Pipe couplings METAL & PIPELINE ENDURANCE Ltd and H ARMSTRONG 29 Jan 1970 [7 March 1969] 35263/72 Divided out of 1302027 Heading F2S An electrically insulating coupling between pipe hubs 10, 11 having flanges 12, 13 at their ends with an insulating gasket 17 between them, comprises a surrounding segmental ring 24 having an annular recess 25 with one side face 27 inclined to a plane normal to the coupling axis, one side face 51 normal to the coupling axis, and a wedge-shaped insulating gasket 52 between the recess face 51 and an inclined face 23 on the hub flange 11, the ring segments 24 being driven towards each other, e.g. by bolts (37), Fig. 1 (not shown), to clamp the joint. Recesses 81 between the hubs contain 0-rings. Terminals (39, 40), Fig.1 (not shown), are provided on the hubs 10, 11 to permit electrical testing of the insulation. When the coupling has been assembled, a plate (56) is welded between flanges (36) at the ends of the ring segments 24, and may be inscribed with service information.
