Abstract

Pakningsanordning for brønnhode, for tetning mellom et første rørelement (14) og andre rørelement (16) som befinner seg i det minste delvis inne i det første rørelementet (14), konsentrisk med dette, idet det første rørelementet (14) har en innerdiameter som er større enn ytterdiameteren til det andre rørelementet (16), slik at det er dannet et ringformet rom (18) mellom rørelementene (14, 16). Pakningsanordningen omfatter et ringformet, elastomert element (10) med hovedsake- lig rektangulær tverrsnittsform, med en første og andre radial flate (11, 13) og en indre og ytre aksial flate, idet den indre aksiale flaten har et konvekst parti (20) med større radial dimensjon enn det ringformede rommet (18), mens den ytre aksiale flaten har et konkavt parti (22) . I det minste en fjær (24) befinner seg i elementet, omtrent i overgangen mellom i det minste en av de radiale flater (11, 13) og den indre aksiale flaten, og har en diameter som er i det minste omtrent 1,5 ganger den radiale dimensjon til det ringformede rommet (18).Wellhead packing means for sealing between a first pipe member (14) and second pipe member (16) located at least partially within the first pipe member (14), concentric therewith, the first pipe member (14) having an inner diameter which is larger than the outer diameter of the second tubular member (16), so that an annular space (18) is formed between the tubular members (14, 16). The packer comprises an annular, elastomeric member (10) of substantially rectangular cross-sectional shape, having a first and second radial face (11, 13) and an inner and outer axial face, the inner axial face having a convex portion (20) with greater radial dimension than the annular space (18), while the outer axial surface has a concave portion (22). At least one spring (24) is in the element, approximately in the transition between at least one of the radial surfaces (11, 13) and the inner axial surface, and has a diameter which is at least about 1.5 times the radial dimension of the annular space (18).
