Abstract: An electrolysis facility having a sealed coupling between at least two pipes may be mountable on one another. The sealed coupling may be formed on at least one overlapping pipe pair by lateral surfaces abutting one another. The pipes may be mounted/mountable one inside the other in a floating manner relative to one another in an axial direction. A deformation point may be formed at a circumferential position having an axial length on a free end of the outer pipe in the overlap region. The deformation point may define a region for deformation of the outer pipe. A lateral surface of an inner lateral surface of the outer pipe and an outer lateral surface of the inner pipe may define a sealing surface that overlaps the deformation point in the axial direction. In addition to high operational reliability, this also enables a simplification of the installation procedure.
