Pulsed Eddy Current (PEC) is an advanced Non-Destructive Testing (NDT) method used to detect corrosion, erosion, and wall thickness loss in ferromagnetic materials such as carbon steel. PEC technology allows inspection through insulation, coatings, fireproofing, weather jackets, and marine growth without the need for insulation removal.
This technique is widely used for corrosion under insulation (CUI) assessments, providing a cost-effective and efficient solution for asset integrity management.
PEC works by generating a pulsed electromagnetic field into the material using a probe. The response signal produced from the material is measured and analyzed to determine wall thickness variations and metal loss.
The technology evaluates the decay of eddy currents within the material, enabling the identification of corrosion and thickness reduction even when the surface is covered by insulation or coatings.
PEC inspection helps identify hidden corrosion without damaging insulation or coatings, allowing operators to optimize maintenance planning, reduce costs, and improve asset reliability.
Our PEC inspection services support proactive integrity management by delivering reliable thickness screening and corrosion assessment for critical assets.
