Abstract

Sonde détectrice servant à examiner l'état de corrosion locale des faces internes de tubes. Elle comporte une source de rayonnement (6) émettant un rayonnement électromagnétique, un détecteur de rayonnement (7) incorporé dans la même unité de structure que la source de rayonnement et destiné à mesurer le rayonnement réfléchi par la face interne du tube, et un élément (3) intercalé entre la source de rayonnement (6) et le détecteur (7), ledit élément (3) étant opaque au rayonnement. La longueur d'onde dudit rayonnement électromagnétique émis par la source de rayonnement (6) est choisi dans une plage où les intensités du rayonnement réfléchi par le métal nu et de celui réfléchi par la surface ayant subi la corrosion sont différentes. Par ailleurs, on a prévu un procédé d'examen de l'état de corrosion locale des faces internes de tubes.
