ABSTRACT:
A flexible joint for transfer of especially a cryogenic fluid includes a first element (3) and a second element (4). The first element (3) comprising an internal, partly curved surface (6), the second element (4) comprising a corresponding outer partly curved surface (8) with at least a sealing element (12,12′) between the curved surfaces (6,8). The first element (3) comprises a first connection part (9) and the second element comprises a second connection part (10) connectable to the first connection part (9) with a flexible part (11, 11′) between the connection of the two connectable parts (9,10) and the sealing element (12). Thereby it is formed a void (16) which may be pressurized with an inert gas at a pressure equal to or higher than the pressure of the fluid to be transferred through the joint.
