Abstract
L~invention concerne un dispositif (54) de modification de conduite susceptible d~être utilisé pour onduler une partie au moins d~une conduite (34). Le dispositif de modification de conduite peut comporter au moins une première pluralité de rouleaux (58) disposés autour d~un passage selon une première configuration. La première pluralité de rouleaux peut former des nervures (36) et des rainures (38) dans le sens de la longueur d~une conduite passant à travers le passage. Une deuxième pluralité de rouleaux (58~) disposés autour du passage selon une deuxième configuration peuvent comprimer des nervures formées par la première pluralité de rouleaux. Les nervures peuvent être formées de telle sorte que la distance entre l~axe central de la conduite et la partie la plus élevée de la surface extérieure d~une nervure soit sensiblement égale à la distance entre l~axe central de la conduite et la surface extérieure de la partie non ondulée (32) de la conduite. La partie ondulée de la conduite modifiée peut se dilater.
