DCVG/ACVG

DCVG/ACVG are survey methods used to gather data that is analyzed to determine if there are any defects to your buried oil, gas, or water pipeline coating.

Applying either direct current (DC) or alternating current (AC) signals to the pipeline, voltage gradients are measured between two calibrated electrodes.
