DELTA GROUP offers Pulsed Eddy Current (PEC) inspection technology for the detection of corrosion areas in carbon and low alloy steels. Measurements are taken through non-conductive material e.g. insulation, protective coatings, concrete and marine growth. It is worth mentioning that DELTA GROUP is based on the pulsed eddy current (PEC) principle which is a reliable way to survey ferrous pipes and vessels through their thermal insulation and protective coatings. The in-depth PEC technology is an excellent tool for prioritizing further inspections. In this technique, the sending coil generates eddy currents at the surface of the material. As they diffuse, they generate a magnetic field that is detected by the receiving coil in the probe. The average remaining wall thickness within the enclosed magnetic field is proportional to the decay time of the received signal.
At DELTA GROUP, we also apply (PEC) technology to penetrate insulation and coating layers that are not magnetic and do not conduct electricity. Furthermore, we use PEC technology to inspect and examine the low alloyed carbon steel substrate underneath metallic weatherproofing sheeting and corrosion products. This approach allows our experts to easily and precisely test, inspect, measure and monitor the actual condition of your assets.
