Abstract
The heating element (14) is in the form of a helical winding (31) made of a resistance heating wire which constitutes the central core of a coaxial cable (32) having a tubular metallic outer sheath and an insulating material interposed between the central core and the outer sheath. The coaxial cable (32) constitutes a helical winding (31). The apparatus can be used in particular for the heat treatment of the small bends of a bundle of tubes in a steam generator in a pressurized water nuclear reactor.
