Abstract

Oppfinnelsen vedrører en klemmeinnretning for anordning i forbindelse med et rør (1) og innbefattende en ytre klemmestruktur (10) for anordning rundt et rør (1), minst ett trykkstempel (12) og minst ett pakningselement (13, 17) som er anordnet mellom trykkstempelet (12) og den ytre klemmestmkturen (10) eller et annet trykkstempel (12), som er anordnet bevegbart i forhold til den ytre klemmestmkturen (10). Trykkstempelet (12) har en høytrykksflate (20) som er eksponert mot et fluid med et høyere trykk rundt klemmeinnretningen, og minst én pakningstrykkflate (26, 27) i anlegg mot pakningselementet (13, 17). Høytrykksflaten (20) har et større areal enn pakningstrykkflatene (26, 27).
