Patent

CA 2474863

The invention relates to a method for loosening and fragmenting scale (2) from the inside of particularly long and/or bent pipelines with pipe (1), characterized in that: - a line/cable (4) is blown through the pipe (1) with a gas flow (3) under pressure, in that the friction between the gas flow (3) and the length of the line/cable (4) results in a rapid transport of the line/cable (4) through the pipe (1), - a nozzle head (6) connected to a hose (7) for supplying water under high pressure is attached to the outer end of the line/cable (4), - the line cable (4) is pulled back while the water spouting from the nozzle head under pressure, forming at least a water jet (8), cuts up and crushes the scale (2) into fragments (2'), said fragments (2') then being fluidised in the gas flow (3), where the water jet (8) after purging forms an aerosol fog which is mixed in with the gas flow (3) forming a three-phase regime, - the supplied gas is transported out through the pipe (1).

Cette invention concerne un précédé visant à éliminer et à fragmenter les dépôts incrustés (2) sur les surfaces intérieures de canalisations particulièrement longues et/ou coudées comprenant des conduites (1), lequel procédé se caractérise en ce qu'il consiste : à gonfler un tuyau/câble (4) dans la conduite (1) avec un flux gazeux (3) sous pression, lequel tuyau/câble (4) étant transporté à grande vitesse dans la conduite (1) sous l'effet de la friction générée entre le flux gazeux (3) et la longueur du tuyau/câble (4 ; à fixer une tête de gicleur (6) reliée à un tuyau flexible (7) chargé d'acheminer de l'eau sous haute pression sur l'extrémité externe du tuyau/câble (4) ; à retirer le tuyau/câble (4) pendant que l'eau, jaillissant de la tête de gicleur sous l'effet de la pression et formant au moins un jet d'eau (8), fragmente et concasse les dépôts incrustés (2) en fragments (2') qui sont ensuite fluidisés dans le flux gazeux (3). Le jet d'eau (8), une fois le nettoyage terminé, forme un brouillard mélangé dans le flux gazeux (3), produisant un régime en trois phases, le gaz utilisé étant ensuite évacué par la conduite (1).
