Title (EN) METHOD FOR DISPENSING ABRASIVES INTO A GAS STREAM FOR CLEANING PIPE INTERIORS
(FR) PROCÉDÉ DE DISTRIBUTION D'ABRASIFS DANS UN FLUX GAZEUX POUR LE NETTOYAGE DES PARTIES INTÉRIEURES D'UN TUBE
Abstract:
(EN) The present is in one embodiment a method for gas stream metal pipe cleaning comprising streaming projectiles within the pipe to a longitudinal momentum of between 3.385 x 10^-3 and 1.760 x 10^-1 Newton seconds. In another embodiment it is a method for gas stream metal pipe cleaning comprising streaming projectiles within the pipe to a longitudinal momentum of between 2.03 x 10^-4 and 1.206 x 10^-1 Newton seconds.
(FR) La présente invention concerne, selon un mode de réalisation, un procédé de nettoyage de tube métallique de flux gazeux comprenant l'écoulement de projectiles à l'intérieur du tube selon un moment longitudinal compris entre 3,385 x 10^-3 et 1,760 x 10^-1 Newton seconde. Un autre mode de réalisation concerne un procédé de nettoyage de tube métallique de flux gazeux comprenant l'écoulement de projectiles à l'intérieur du tube selon un moment longitudinal compris entre 2,03 x 10^-4 et 1,206 x 10^-1 Newton seconde.
