Abstract
This study aims to analyze and use MFL technology as an effective tool in nondestructive
testing (NDT) to detect defects such as cracks and corrosion in drill pipes,
through 3D simulation and experimental studies. In fact, the comparison of the
simulation results to experimental ones shows a good concordance. In addition, the
simulation and experimental study make in evidence the effect of some electrical and
mechanical parameters on defect detection sensitivity such as coils excitation density,
its dimensions, scanning speed and defect orientation and dimensions. In context, we
recall that many researchers had presented and validated some solution to compensate
the effect of lift-off variation and acceleration velocity.
