Corrosion monitoring of pipelines and pipework under extreme conditions (underwater and high temperature) is an important task as corrosion is one of the leading causes of failure these parts of industrial plant. The Magnetic Flux leakage technique has the potential to be adapted to these extreme conditions. Initial designs of an installed sensor for measuring pipe wall, thickness are examined by a three dimensional simulation FEM model using COMSOL software. This was carried out with an experimental set-up including the same pipe samples of various thickness measured along an axial line. Hall effect and GMR sensors were tested, together with different magnetic materials. This paper discusses the results obtained through FEM simulation and compares these with experiment, together with the wired/wireless data transmission this confirms the potential of the system for three-dimensional enhanced MFL inspection.
