Abstract (en)
The device and method prevents corrosion of a previously heated insulated metallic casing (1) containing internal metallic parts (2, 3) which are sensitive to corrosion. The device comprises an external electrical system for maintaining the temperature of the casing. This system consists of at least one localised surface element (10, 11, 12, 13) for the electrical heating of the casing by conduction. The system is so arranged that a temperature above a predetermined threshold temperature is maintained at all points on the casing. <IMAGE>

Dispositif et procédé de protection contre la corrosion d'une enceinte métallique (1) calorifugée, préalablement chauffée, comprenant des parties métalliques internes (2,3) sensibles à la corrosion. Le dispositif comporte des moyens électriques externes de maintien en température de l'enceinte comprenant au moins un élément surfacique local (10, 11, 12, 13) de chauffage électrique par conduction de l'enceinte, lesdits moyens étant agencés pour maintenir une température en tous points de l'enceinte, supérieure à une température seuil déterminée. <IMAGE>
