Abstract
A thick non-magnetic metal plating (18) constituting a sleeve on the surface of the tube (12) is produced by electroplating a region to be repaired. The plating has a thickness greater than 0.5 mm, and preferably close to 1 mm, and by itself can ensure the mechanical integrity of the tube in service. Preferably, the thick non-magnetic plating is made of a nickel-boron alloy with less than 5% by weight of boron.
