The present invention relates to a pressure vessel (1) for a high pressure press comprising at least a first sub-cylinder (4) and a second sub-cylinder (6), which are axially connected to form a cylinder body (2) for enclosing a high pressure medium, and a sealing arrangement arranged at the inner wall of the cylinder body for sealing the joint (3) between the first and the second sub-cylinder (4, 6) against leakage of the pressure medium. The sealing arrangement is comprising a ring shaped sealing band (18), a first circumferential protruding flange (30), which is arranged on the inner wall of the first sub-cylinder and which axially extends from the joint (3) and away from the second sub-cylinder (6), and a second circumferential protruding flange (32), which is arranged on the inner wall of the second sub-cylinder (6) and which axially extends from the joint (3) and away from the first sub-cylinder (4). The sealing band (18), in mounted position, is located concentrically within the first and the second protruding flanges (30, 32) such that it in a radially pre-stressed manner abuts against the first and second protruding flanges (30, 32) and sealingly overlaps the joint (3) between the first and the second sub-cylinder (4, 6). The sealing arrangement further comprises a first circumferential mounting space (51), which is arranged in the inner wall of the first sub-cylinder (4) and which axially extends from the first protruding flange (30) and away from the second sub-cylinder (6), for facilitating exchange of components of the sealing arrangement.

L'invention concerne un récipient sous pression (1) pour presse haute pression. Le récipient sous pression comprend au moins un premier sous-cylindre (4), un second sous-cylindre (6) qui sont reliés axialement afin de former un corps cylindrique (2) destiné à enfermer un milieu haute pression, et un agencement d'étanchéité situé sur la paroi intérieure du corps cylindrique pour étanchéifier le joint (3) entre le premier et le second sous-cylindre (4, 6) contre les fuites du milieu sous pression. L'agencement d'étanchéité est composé d'une bande d'étanchéité en forme d'anneau (18), un premier rebord périphérique faisant saillie (30), qui est placé sur la paroi intérieure du premier sous-cylindre et qui s'étend axialement à partir du joint (3) et s'écarte du second sous-cylindre (6), et un second rebord périphérique faisant saillie (32), qui est placé sur la paroi intérieure du second sous-cylindre (6) et qui s'étend axialement à partir du joint (3) et s'écarte du premier sous-cylindre (4). La bande d'étanchéité (18), en position montée, est située de manière concentrique à l'intérieur du premier et du second rebord faisant saillie (30, 32)de sorte qu'elle vient buter de manière radialement précontrainte contre le premier et le second rebord faisant saillie (30, 32) et recouvre le joint (3) de manière étanche entre le premier et le second sous-cylindre (4, 6). L'agencement d'étanchéité comprend également un premier espace de montage périphérique (51), qui est situé dans la paroi interne du premier sous-cylindre (4) et qui s'étend axialement à partir du premier rebord faisant saillie (30) et s'écarte du second sous-cylindre (6), pour faciliter l'échange de composants de l'agencement d'étanchéité.
