ABSTRACT:
An axially flexible sealing device connecting two pipeline ends which comprises a number of sealingly connected annular members, each annular member including an inner cylindrical member, two spaced apart outer cylindrical members, and separate flexible ring members connecting the outer cylindrical members to the inner cylindrical member, each outer cylindrical member having a portion extending axially beyond the adjacent end of the inner cylindrical member when the attached flexible ring member is in an untensioned state. The sealing device is designed for use in connecting two pipelines located beneath sea level wherein the end of one of the pipelines is located in a hollow structure and one of the sealing devices is connected thereto, whereas the other end of the sealing device is sealingly connected to one end of a penetration sleeve which is sealingly connected through the wall of the structure (the other end of the sleeve being connected to the end of the other pipeline).
