Title
(EN) METHOD FOR REHABILITATING A PIPELINE WITH A LINER
(FR) PROCÉDÉ DE RÉNOVATION DE CONDUITE AVEC UN REVÊTEMENT
Abstract
(EN)
A method for rehabilitating a pipeline with a liner is described. The method includes providing a coupling member 1 configured to connect a liner to a pipeline element. The method uses an alignment device 6. A first alignment element 6 of the device is connected to an end of the host pipe 3 and a second alignment 6 element of the device to an end of the coupling member to axially align both components. A length of the liner 2 is provided through the host pipe 3 and the coupling member to expose a joining section of the liner outside the host pipe 3 The coupling member 1 is brought towards the host pipe 3 such that the first and second alignment elements 6 mate and the joining section of the liner is received in the coupling member 1. The joining section of the liner is then pressurized to bring it against an interior surface of the coupling member 1, and the curable resin composition of the liner is cured to form a functional joint between the coupling member 1 and the liner joining section.

L'invention concerne un procédé pour rénovation de conduite avec un revêtement. Le procédé comprend la fourniture d'un élément d'accouplement (1) conçu pour relier un revêtement à un élément de conduite. Le procédé utilise un dispositif d'alignement (6). Un premier élément d'alignement (6) du dispositif est relié à une extrémité du tuyau hôte (3) et un second élément d'alignement (6) du dispositif à une extrémité de l'élément d'accouplement pour aligner axialement les deux composants. Une longueur du revêtement (2) est introduite dans le tuyau hôte (3) et l'élément d'accouplement pour exposer une section de jonction du revêtement à l'extérieur du tuyau hôte (2). L'élément d'accouplement (1) est amené vers le tuyau hôte (3) de telle sorte que les premier et second éléments d'alignement (6) s'accouplent et la section de jonction du revêtement est reçue dans l'élément d'accuoplement (1). La section de jonction du revêtement est ensuite mise sous pression pour l'amener contre une surface intérieure de l'élément d'accouplement (1), et la composition de résine durcissable du revêtement est durcie pour former un joint fonctionnel entre l'élément d'accouplement (1) et la section de jonction de revêtement.
