Abstract

La présente invention se rapporte à des procédés et à des systèmes destinés au nettoyage abrasif, à l'ébavurage de tuyaux, à la mise en place de revêtements protecteurs et au colmatage des fuites dans des tuyaux existants, en une seule opération. Un système de tuyauterie peut être nettoyé en un seul passage par des jets intermittents de particules sèches qui sont poussées et tirées par l'air tout au long du système de tuyauterie par un générateur et un aspirateur. Les tuyaux peuvent être protégés des effets de la corrosion, de l'érosion-corrosion et de l'électrolyse de l'eau, prolongeant la durée de vie des systèmes de tuyauterie tels que la tuyauterie en cuivre, en acier, en plomb, en laiton, en fonte et matériaux composites. Les techniques de nettoyage et de revêtement protecteur décrites sont efficaces dans des tuyaux faisant jusqu'à 2 pouces (5,08 cm) de diamètres, si bien que l'ensemble des systèmes de tuyauterie peut être nettoyé de façon abrasive, revêtu et colmaté. Le produit de colmatage de fuite d'une épaisseur d'environ 4 mils (0,10 mm) peut recouvrir l'intérieur des tuyaux. Les systèmes de tuyauterie peuvent être remis en service approximativement dans les 24 à 96 heures.
