摘要:
A tubular joint comprising first and second tubular members, an annular sealing element positioned between the tubular members and a clamping device for clamping the tubular members to each other with an end face of the first tubular member in contact with an end face of the second tubular member. The sealing element comprises an annular metallic body. Two sealing surfaces on the metallic body are designed to mate with tapered sealing surfaces on the tubular members. A first spring-energized polymeric seal member is mounted to the metallic body and configured to be in sealing contact with a radially extending sealing surface on the first tubular member. A second spring-energized polymeric seal member is mounted to the metallic body and configured to be in sealing contact with a radially extending sealing surface on the second tubular member. Seal members are prestressed upon clamping of the tubular members to each other.
