Abstract
The invention relates to a sealing joint for pipes (3) or pipe sockets (2) in, for example, a nuclear reactor. The joint comprises at least two sealing bodies (4, 5) contacting each other in a contact surface (8) and provided with through holes (6, 7). The holes (6, 7) are delimited by envelope surfaces (9, 10) and form a tubular channel (11) through the sealing bodies (4, 5) and the contact surface (8). The sealing bodies (4, 5) are displaceable in relation to each other along the contact surface (8). Around the channel (11) a sealing member (12) is arranged between the sealing bodies (4, 5). Each one of the sealing bodies (4, 5) is divided into at least two discs (4a, 4b; 5a, 5b, respectively) in a plane intersecting the associated envelope surface (9, 10) along a closed curve. Between the discs belonging to a sealing body (4, 5), a slot (13 ) has been provided which is delimited by the associated envelope surface (9, 10). A flexible sealing ring (13a) is inserted into the slot (13). When the discs are compressed, the volume of the slot (130 is adapted to be reduced, causing the inserted sealing ring to be partially pressed out of the slot and towards, for example, a pipe (3) loc…
