Title (EN) METHOD OF LINING PIPES
(FR) PROCEDE PERMETTANT DE GARNIR DES TUYAUX
Abstract:
(EN) In a method of lining a pipe (3) a lining pipe (1) of thermoplastics material is inserted into the pipe (3) to be lined. The lining pipe (1) is of smaller diameter than the pipe (3) to be lined, and the thermoplastics material incorporates a cross-linking agent. The lining pipe (1) is then caused to expand into contact with the pipe (3) to be lined, and the thermoplastics material is cross-linked.
(FR) L'invention a trait à un procédé permettant de garnir un tuyau (3). Selon ce procédé, une garniture interne (1) composée d'une matière thermoplastique est introduite à l'intérieur du tuyau (3). Cette garniture interne (1) présente un diamètre plus petit que celui du tuyau (3). La matière thermoplastique contient un agent de réticulation. On provoque ensuite l'expansion de la garniture interne (1) jusqu'à ce qu'elle vienne au contact du tuyau (3), puis la matière thermoplastique est réticulée.
