Abstract

Selon l'invention, un procédé de raccordement d'un premier tuyau (1) à un second tuyau (1) comprend les étapes suivantes: - raccorder le premier tuyau au second tuyau (1) au moyen d'une bride femelle (2) et d'une bride mâle (3) après alignement central du premier et du second tuyau l'un avec l'autre, avant l'étape de raccordement du premier tuyau au second tuyau (1), chaque bride (2,3) étant fixée rigidement et mécaniquement au tuyau respectif (1) par expansion de la paroi de chaque tuyau (1) vers la surface interne de chaque bride (2, 3), l'étape d'expansion étant effectuée par application de pression depuis l'intérieur du tuyau au moyen d'une machine d'expansion pourvue de galets qui tournent le long de la circonférence de la paroi interne du tuyau, tandis qu'ils engendrent la pression d'expansion, amenant la bride femelle (2) et la bride mâle (3) ensemble, suivi de leur fixation rigide aux tuyaux respectifs (1).
