ABSTRACT:
A flangeless, disc-like seal plate is disclosed for insertion between opposing flowline hubs for sealingly connecting, blocking or rerouting fluid flow between various fluid carrying lines within said flowline hubs. For connecting flow lines, straight throughbores within the seal plate are provided with V-seals in channels on said seal plate around the throughbores, as well as O-ring seals around said V-seals and another O-ring near the periphery of the disc itself. No seals or seal grooves are necessary on the hub faces. For connecting hydraulic control lines, the seal plate is equipped with transverse channels interconnecting various throughbores but may also be provided with blind ports for totally blocking off certain control lines at the plate. Within said throughbores, fluid diverter plugs are inserted which are either equipped with protruding caps for opening up corresponding check valves housed within hub lines or flush plugs such that said check valves remain closed after clamp-up. Through this arrangement various lines may either be blocked, be fluidly connected, or have their fluid flow rerouted internally without rearranging the alignment between the lines within the flowline bundle.
