Title (EN) ULTRASONIC CATHODIC PROTECTION TEST STATION
(FR) POSTE DE CONTRÔLE DE PROTECTION CATHODIQUE ULTRASONORE
Abstract:
(EN) Ultrasonic transducers are imbedded into sacrificial metal coupons which are located in the vicinity of underground or aboveground structures, such as a pipe or tank, which allow for the measurement of the effectiveness of impressed current cathodic protection systems and can be used to determine the corrosion rate of the structure that is being protected. When excited by a pulser-receiver excitation pulse, the ultrasonic transducers can be used to determine the thickness of the coupon and its rate of change over time. The sacrificial metal coupon ultrasonic transducer assembly can be located in the vicinity of underground piping, under or inside of a tank, underground or underwater, or inserted into structures where absolute material loss values or material loss rate of change is being monitored.
(FR) L'invention concerne des capteurs ultrasonores qui sont incorporés dans des coupons de métal sacrificiel qui sont situés au voisinage de structures souterraines ou au-dessus du sol, telles qu'un tuyau ou un réservoir, qui permettent la mesure de l'efficacité de systèmes de protection cathodique par courant imposé et peuvent être utilisés pour déterminer le taux de corrosion de la structure qui est en cours de protection. Lorsqu'il est excité par une d'impulsion d'excitation de générateur d'impulsions-récepteur, les capteurs ultrasonores peuvent être utilisés pour déterminer l'épaisseur du coupon et son taux de changement au cours du temps. L'ensemble capteur ultrasonore à coupon de métal sacrificiel peut être situé au voisinage d'une tuyauterie souterraine, sous ou à l'intérieur d'un réservoir, sous le sol ou sous l'eau, ou inséré dans des structures dans lesquelles les valeurs absolue de perte de matériau ou la vitesse de changement de perte de matériau est en train d'être surveillée.
