Abstract
Des méthodes permettent de produire un compensateur de dilatation en fournissant une doublure de plastique interne comportant une première et une deuxième extrémités espacées, une surface extérieure et un volume intérieur se prolongeant de la première extrémité à la deuxième extrémité; en positionnant la doublure de plastique interne à lintérieur dun conduit métallique allongé, le conduit métallique allongé comportant une première et une deuxième extrémités espacées, une surface interne, une surface externe et une section de dilatation/contraction; chauffant la doublure de plastique interne; en appliquant une pression sur un fluide positionné dans le volume intérieur de la doublure de plastique interne en vue de dilater la doublure de plastique interne là où la doublure de plastique interne comporte une section de dilatation/contraction et en refroidissant la doublure de plastique interne.
