: Variations in signal strength indicate where current is escaping the pipe through a coating defect.

: Operators use Excel templates to log coordinates, burial depth, signal readings (in decibels or microvolts), and the status of excavations. For instance, reports like those found on Scribd summarize inspection data for specific pipeline segments. Download ACVG xlsx

ACVG surveys identify areas where a pipeline’s protective coating has failed, known as "," which expose the steel to the soil and increase corrosion risk. : Variations in signal strength indicate where current

: An AC signal is injected into the pipeline via a transmitter. Technicians use specialized equipment, such as an A-frame with spikes, to measure the voltage gradient in the soil. signal readings (in decibels or microvolts)
