Abstract
Tetningsanordning for produksjonsrøroppheng i brenn, omfattende en metall-mot- metall-tetning (5) som aktiveres av en drivhylse (1). Drivhylsen er skrudd inn på utsiden av røropphenget, og kommer, ved å skrus nedover, til anlegg mot en trykkring (4), som aktiverer metall-mot-metall-tetningen (5) ved å komprimere denne mellom en skulder (27) på utsiden av røropphenget og innsiden av rørhodet. Oppfinnelsen omfatter dessuten en delt ring (3) som drives inn i et spor (8) i innsiden av rørhodet, for å hindre at tetningen (5) drives ut på grunn av trykk nedenfra.Sealing device for fire production pipe suspension comprising a metal-to-metal seal (5) actuated by a drive sleeve (1). The drive sleeve is screwed in on the outside of the pipe suspension and, by screwing downwards, comes into contact with a pressure ring (4), which activates the metal-to-metal seal (5) by compressing it between a shoulder (27) on the outside of the pipe suspension and the inside of the pipe head. The invention further comprises a split ring (3) driven into a groove (8) inside the tube head, to prevent the seal (5) from being driven out from below pressure.
