In-line inspection of pipeline crack based on biased AC field measurement

Objective The traditional magnetic flux leakage (MFL) testing technique for pipelines has been found to be insufficient in detecting crack defects with a small angle to the magnetic field lines. As a result, an inspection method that can accurately detect such defects is urgently needed to ensure th...
