Title (EN) CAM-ASSISTED WEDGE ACTUATED, METAL-TO-METAL SEAL, BLOCK AND BLEED PLUGGING TOOL
(FR) OUTIL D'OBTURATION DE BLOCAGE ET DE PURGE, A JOINT METAL SUR METAL, A COMMANDE DE COIN ASSISTE PAR CAME
Abstract:
(EN) A method of plugging a pipe including sealably securing onto its exterior first and second spaced apart collars, (12,14) the collars having sealing faces (18, 20) each in a plane perpendicular the pipe, (42, 44) cutting and removing a length of pipe from between the collars (12, 14) leaving two open pipe ends (42, 44), positioning first and second seal cups (66, 68) between the collars, the seal cups having forwardly extending circumferential lips (102, 104) of internal diameter greater than the external diameter of the pipe, seal cups (66, 68) having top and bottom cam followers (72, 74, 78, 80), moving cam surfaces (82, 84, 86, 88) against the cam followers to guide the seal cups (66, 68) into sealing engagement with the sealing faces (18, 20) of the collars (12, 14), and forcing a wedge (48, 50) between rearward surfaces of the seal cups (66, 68).
(FR) La présente invention a trait à un procédé d'obturation d'une canalisation comprenant la fixation étanche sur son extérieur des premier et deuxième collets espacés (12, 14), les colliers présentant des faces d'étanchéité (18, 20) chacune dans un plan perpendiculaire à la conduite (42, 44), la découpe et l'élimination d'une longueur de conduite de la partie entre les colliers (12, 14) en laissant subsister deux extrémités de conduite ouvertes (42, 44), le positionnement de première et deuxième coupelles de joint présentant des bords périphériques s'étendant vers l'avant (102, 104) de diamètre intérieur supérieur au diamètre extérieur de la conduite, des coupelles de joint (66, 68) comprenant des galets de came (72, 74, 78, 80), des surfaces mobiles de came (82, 84, 86, 88) contre les galets de came pour guider les coupelles de joint (66, 68) en engagement d'étanchéité avec les faces d'étanchéité (18, 20) des colliers (12, 14) et la poussée en force d'un coin (48, 50) entre des surfaces s'étendant vers l'arrière des coupelles de joint (66, 68).
