7. Front and back arrows and dB values to indicate the location of the damaged points on coatings during detection of the damaged points on coatings.
Pipeline location and depth investigation principle:
multi-purpose full-frequency pipeline detector detects underground pipelines electromagnetically, which applies signals to metal pipelines through the transmitter, generates pipeline current in metal pipelines and secondary magnetic field around pipelines, and measures the secondary magnetic field of pipelines on ground through the receiver, in order to accurately determine the location, buried depth, running direction, route, and signal current intensity of pipelines.
Leakage testing on anti-corrosive coatings principles
An electrical signal is sent to the underground metal pipeline through the transmitter. In case damaged points exist on the underground pipeline coating, they are short-circuited with the earth, generating creepage current radiating all around, with the most intensive radiation above the damaged points. Based on that, the damaged points on coatings are found.
