Flexible Joint for Cryogenic Pipe

Flexible joint for transfer of a fluid, for instance a cryogenic fluid, comprising a first element and a second element each able to be connected to respective fluid transfer elements, the first element comprising a first through going opening comprising an internal, partly curved surface, the second element comprising a second through going opening and an outer partly curved surface corresponding to the internal curved surface of the first element and the first and second through going openings are in communication with each other, where the first element comprises a first connection part and the second element comprises a second connection part connectable to the first connection part forming a sealed connection between the two connectable parts, where there are provided a flexible part between the connection of the two connectable parts, wherein at least one sealing element between the curved surfaces and the sealing element, on one or both sides of the connection formed by the two connectable parts, which, when connected, forms a void between the sealing connection between the connectable parts and the sealing element, where a void between two sealing means is pressurized with an inert gas at a pressure equal to or higher than the pressure of the fluid to be transferred through the joint.
