Pulsed Eddy Current (PEC) is an electromagnetic screening tool used to detect degradation and defects in ferromagnetic materials. It provides relative wall thickness measurements through non-metallic pipe protection. PEC can acquire average wall thickness measurements without removing insulation or coating and can penetrate most forms of insulation, including cementitious types up to 10 inches thick. PEC can be utilized on in-service equipment and can easily be performed via rope access.
