Abstract

L'outil 18, qui est adapté sur l'extrémité du tuyau 10, comporte une membrane cylindrique 21 entourant un noyau rigide 19, et une enceinte 20 comportant une cavité annulaire 44 réalisée de façon à recevoir l'extrémité 17 ramollie par chauffage du revêtement 16 en matière plastique, qui entoure la membrane. Un fluide sous pression est introduit dans la membrane pour la gonfler rapidement et évaser radialement l'extrémité du revêtement. La membrane peut être formée en un élastomère vulcanisable à la température ambiante. La matière plastique est chauffée avant son évasement de façon à être suffisamment ramollie pour pouvoir être déformée sans conserver de tensions résiduelles. L'invention est applicable, notamment, aux tuyaux métalliques doublés d'un revêtement en fluorure de polyvinylidène.
