Title (EN) PIPE LINING
(FR) GARNITURE INTERIEURE DE TUYAUX
Abstract:
(EN) A lining method for a host pipe (10) including lubrication of the host pipe (10) prior to insertion of a thermoplastic liner (11) using tight fit techniques. After allowing the inserted liner (11) to relax, the liner (11) is partially pulled from within the host pipe (10) and clamped to allow fitting of a special flange (40) thereto by butt fusion, for example. Thereafter the liner (11) is allowed to revert so as to abut a flange (12) fitted to the host pipe (10). The technique is repeated at the other pipe end.
(FR) L'invention concerne un procédé permettant de réaliser la garniture de tuyaux (10) et destiné à un tuyau hôte (10). Ce procédé consiste à lubrifier le tuyau hôte avant l'insertion d'une garniture thermoplastique (11) par la voie de la technique de l'ajustement serré. Après détente de la garniture (11) insérée, celle-ci est partiellement extraite de l'intérieur du tuyau hôte (10) et bridée en vue de permette l'ajustement d'une bride spéciale (40) au niveau de son extrémité, par fusion de leurs bouts respectifs, par exemple. La garniture (11) peut donc être réintroduite dans le tuyau de manière que son extrémité aboute contre une bride (12) adaptée au tuyau hôte (10). Cette technique est répétée au niveau de l'autre extrémité du tuyau.
