In order to make the sealing for the intersection zone (AB) of the joints (A, B) of a pressure vessel assembled from a plurality of parts leaktight and easy to disassemble, a seating surface (13) for a lid flange (11) is provided on the outer surfaces of the joint flanges (5, 6, 7, 8) in the intersection zone (AB) of the joints (A, B). In addition, the lid flange (11) is secured releasably on the seating surface (13). A sealing of this kind is suitable, in particular, for the cruciform joints of steam-turbine casings. <IMAGE> |
