Title (EN) DEVICE AND METHOD FOR REPAIRING PIPE USING HYDROPHILIC SEALS
(FR) DISPOSITIF ET METHODE POUR REPARER UNE CONDUITE AU MOYEN DE JOINTS HYDROPHILES
Abstract: front page image
(EN)A liner tube is provided for repairing either a single pipe line or a main pipe line (50) having a lateral pipe line (52) connected thereto. The liner tube assembly (10) includes a liner tube (14) impregnated with a liquid material capable of curing and hardening. The liner tube includes two hydrophilic sealing members(56, 58) positioned on opposite sides of the damaged portion of the pipe line. The hydrophilic seals (56, 58), when encountering liquid expand and form a liquid tight seal between the liner tube and the pipe line.
(FR)L'invention concerne un tube manchon pour réparer soit une conduite unique, ou une conduite principale (50) présentant une conduite latérale (52) reliée à celle-ci. L'assemblage de tube manchon (10) de l'invention comprend un tube manchon (14) imprégné d'une matière liquide permettant un séchage et un durcissage. Le tube manchon comprend deux éléments d'étanchéité hydrophiles (56, 58) positionnés sur les côtés opposés de la partie endommagée de la conduite. Les joints hydrophiles (56, 58), une fois en contact avec le liquide, se dilatent et forment un joint étanche au liquide entre le tube manchon et la conduite.
