Title (EN) METHOD FOR JOINING AND/OR SEALING THERMOPLASTIC PIPES
(FR) PROCEDE DE RACCORDEMENT ET/OU DE JONCTION ETANCHE DE TUYAUX THERMOPLASTIQUES
Abstract: front page image
(EN)The invention relates to a method for joining and/or sealing thermoplastic pipes (1 a, lb) by positioning the ends to be joined to abut each other. The invention is characterized in that a thermoplastic sheet (2) or sleeve is applied around the abutting pipe ends and welded to the pipe walls to obtain a welded pipe joint by clamping a heating band element (3) around the thermoplastic sheet (2) or sleeve, which element is removed after finished welding operation.
(FR)La présente invention concerne un procédé de raccordement et/ou de jonction étanche de tuyaux thermoplastiques (1a, 1b) qui consiste à positionner les extrémités devant être couplées de manière à ce qu'elles butent l'une contre l'autre. Cette invention se caractérise en ce qu'une feuille (2) ou une gaine thermoplastique est appliquée autour des extrémités aboutées des tuyaux et soudée sur la paroi des tuyaux pour former ainsi un joint soudé, par serrage d'un élément (3) formant bande chauffante, autour de la feuille (2) ou gaine thermoplastique, ledit élément étant enlevé lorsque l'opération de soudure est terminée.
