ABSTRACT:
For repairing the tubes (2') of a steam generator (1), an impervious metallic sleeve is formed along the defective area (26) of the internal wall of a tube (2') by a wet process. The surface treatment is carried out on the spot in the tube (2') by means of a nickel solution free from chlorine, preferably a nickel sulphamate solution free from chlorine.
