Abstract

Método para detectar micro-poros (8) en depósitos de doble capa que comprenden una carcasa exterior (1) y una capa interna (2), donde entre la carcasa exterior (1) y la capa interna (2) existe una capa intermedia (3), donde el método comprende: rociar la capa interna (2) del depósito con una disolución acuosa que forma una capa de revestimiento (5) sobre la capa interna (2); inyectar un fluido a presión en el interior de la capa intermedia (3); mantener un determinado valor de presión en el interior de la capa intermedia (3), durante un determinado periodo de tiempo; verificar si se producen burbujas (7) de disolución acuosa en la capa de revestimiento (5); determinar que existen micro-poros (8) en los lugares en donde se observan dichas burbujas (7).Method for detecting micro-pores (8) in double-layer tanks comprising an outer shell (1) and an inner layer (2), where between the outer shell (1) and the inner layer (2) there is an intermediate layer ( 3), where the method comprises: spraying the inner layer (2) of the tank with an aqueous solution that forms a coating layer (5) on the inner layer (2); injecting a pressurized fluid into the intermediate layer (3); maintain a certain pressure value inside the intermediate layer (3), for a certain period of time; check if bubbles (7) of aqueous solution are produced in the coating layer (5); determine that there are micro-pores (8) in the places where said bubbles (7) are observed.
