Inspection Tool for Harsh Environment Operation Utilizing Pulsed Remote Field Technique

Abstract

This paper focuses on design of instrumentation for nondestructive inspection of underground casing pipes, utilizing pulsed remote field technique. The presented inspection tool is designed for high-temperature environment operation, based on a principle of combining thermally `uprated' commercial-grade components with application-specific, high-temperature rated parts. Key design issues regarding the expected measurement performance and reliability of the tool are discussed. Results of laboratory tests have confirmed practical usability of the developed inspection tool for a targeted harsh-environment application
