SEALING COUPLING BETWEEN AT LEAST TWO PIPES OF AN ELECTROLYSIS SYSTEM THAT CAN BE MOUNTED ON ONE ANOTHER, AND USE THEREOF

The invention relates to a sealing coupling (10) between at least two pipes of an electrolysis system that can be mounted on one another, wherein the sealing coupling is formed on at least one pair ofpipes (11, 13) in an overlapping region (5.1; 15.1) of the pipes via contacting casing surfaces (11.3, 13.1), the pipes of the pair of pipes are/can be floatingly mounted inside one another, relativeto one another in the axial direction, at least one target deformation point (13.7) is formed at a free end of the outer pipe of the pair of pipes, in the overlapping region (15.1) and in a predefined circumferential position (u1, u2) with a predefined axial length, which target deformation point defines a region for a deformation of the outer pipe, and at least one casing surface of the inner casing surface (13.1) of the outer pipe and the outer casing surface (11.3) of the inner pipe defines a sealing surface (11.31, 13.11), which sealing surface overlaps the target deformation point in theaxial direction.
