Title (EN) CLEANING INSIDE AND ADJACENT SERVICE CONNECTIONS IN PREPARATION FOR PIPE LINING METHOD
(FR) NETTOYAGE DE L’INTÉRIEUR ET À PROXIMITÉ DE BRANCHEMENTS D’EAU EN VUE D’UN PROCÉDÉ DE REVÊTEMENT INTÉRIEUR DE TUYAUX
Abstract:
(EN) The present inventions are methods for cleaning pipes with service connections by vacuuming therethrough abrasive projectiles first in one direction, and thereafter, in an opposing direction, with additional cleaning achieved by opening of service connection valves during vacuuming. By opening service connection valves during vacuuming, debris and moisture are removed from within the service connections. Vacuuming direction reversal removes shadow deposit areas.
(FR) La présente invention concerne des procédés de nettoyage de conduites, ayant des branchements d’eau, par aspiration à l’intérieur de ces derniers de projectiles abrasifs, tout d’abord dans une première direction, puis dans une direction opposée, un nettoyage supplémentaire étant effectué pendant l’aspiration. En ouvrant des soupapes de branchement d’eau pendant l’aspiration, des débris ainsi que de l’humidité sont éliminés de l’intérieur des branchements d’eau. L’inversion des directions d’aspiration permet l’élimination de zones d’ombres de dépôt.
