Abstract
Tetningssammenstillingen (10;50) tetter mellom et undervannsbrønnhodehus (12) og en foringsrørhenger ( 6). En hovedtetningsdel (20) av metall inkluderer fingere (32) og (34) og én eller flere elastomere pakninger (38). En øvre tetningsdel (64) kan inkludere gjenger for inngrep med tetningsdelen (20) av metall. Ved fremgangsmåten ifølge oppfinnelsen dannes først en initial elastomer pakning (38) og fluidtrykk utøves fra oversiden for å fiksere høytemperaturmetallpakningen (36).
