Pulsed Eddy Current (PEC)

Pulsed Eddy Current (PEC) is a non-destructive testing method used to assess metal thickness without cutting, drilling, or accessing the far side of the material. The technique works by sending a short electrical pulse into the surface, which generates magnetic fields known as eddy currents within the metal. By monitoring how these fields decay over time, PEC can determine wall thickness, detect corrosion, and identify material loss. It can also inspect metal through coatings, paint, and insulation, making it a fast and safe option that avoids equipment damage or disassembly. With a known original wall thickness, PEC can accurately estimate remaining wall and percentage wall loss in ferrous materials.

Advantages of Pulsed Eddy Current (PEC) 

Using PEC provides several key benefits, including:

• Versatility – Effective on ferrous materials even when covered with coating or insulation.
• Non-contact capability – Measures wall thickness through non-conductive and non-magnetic materials such as concrete and silicate.
• Remote applicability – Can be deployed in hard-to-reach areas.
• Early corrosion detection – Identifies degradation before it becomes a major issue.
•
