ABSTRACT:
Process for corrosion protection of a steam generator tube, in which a metal layer (10) compatible with the material of the tube (1) is deposited by electrolysis on the inner surface of the tube (1) after it is fixed in the tube plate (2), on either side of the face of the plate (2) in contact with the water to be vaporized, over a length which is appreciably greater than the transition zone (5) between the crimped part and the uncrimped part of the tube (1). The outer surface of the tube (1) may also be covered with a metal layer (12) before it is fixed in the tube plate (2). The invention applies, in particular, to steam generators of pressurized water nuclear reactors.
