Abstract

L'invention est du domaine des appareils d'expansion hydraulique pour tubes. L'appareil hydraulique d'expansion pour appliquer un tube contre une plaque tubulaire comprend un mandrin 11 adapté à être introduit dans un tube et comportant des joints annulaires 13, 15 espacés, et un canal débouchant dans l'espace compris entre les joints 13, 15 afin d'y introduire un fluide sous pression, ledit mandrin 11 comportant une partie conique 27 dont la grande base est voisine de son extrémité antérieure, le joint 15 étant disposé autour de cette partie conique 27 et est sollicité vers l'extrémité antérieure du mandrin 11 par un ressort 31. Application à la fabrication des générateurs de vapeur et des échangeurs de chaleur à tubes.
