Title (EN) CORROSION DETECTION SYSTEM
(FR) SYSTÈME DE DÉTECTION DE CORROSION
Abstract:
(EN) A system (1) for detecting and locating corrosion on the outer surface of a metal body (2). The system includes an extended electromagnetic waveguide (6) arranged adjacent to the outer surface of the metal body. The electromagnetic waveguide includes a sacrificial component that experiences substantially the same environment as the outer surface of the metal body. The system also includes a waveform generator (10) arranged to be connected to the waveguide and to inject an electromagnetic waveform into the waveguide. The system also includes a waveform analyser (12) connected to the waveguide. The waveform analyser is arranged to receive a reflected portion of the injected electromagnetic waveform from the waveguide. The reflected portion of the injected electromagnetic waveform is used by the waveform analyser to determine the location of corrosion of the sacrificial component of the waveguide.
(FR) L'invention concerne un système (1) de détection et de localisation de corrosion sur la surface extérieure d'un corps métallique (2). Le système comprend un guide d'ondes (6) électromagnétique étendu disposé adjacent à la surface extérieure du corps métallique. Le guide d'ondes électromagnétique comprend un composant sacrificiel qui subit le même environnement que la surface extérieure du corps métallique. Le système comprend également un générateur de forme d'onde (10) conçu pour être connecté au guide d'ondes et pour injecter une forme d'onde électromagnétique dans le guide d'ondes. Le système comprend également un analyseur (12) de forme d'onde connecté au guide d'ondes. L'analyseur de forme d'onde est conçu pour recevoir une partie réfléchie de la forme d'onde électromagnétique injectée à partir du guide d'ondes. La partie réfléchie de la forme d'onde électromagnétique injectée est utilisée par l'analyseur de forme d'onde pour déterminer l'emplacement de corrosion du composant sacrificiel du guide d'ondes.
