Repair of a steam generator tube is performed by crimping a tubular casing (18) in a zone (14) of the tube (12) in which a metallic coating (20) has been produced on the inner surface of the tube, for example by electrolytic deposition. The tubular casing (18) may consist of an attached sleeve (18), crimped in the tube (12). In the case of a tube crimped over only part of the length of the hole passing through the tube plate, the tubular casing may consist of the tube itself on which additional crimping is performed inside the hole which passes through the tube plate. |
