Questions about electric spark leak detectors
Thread Content
The buried pipes in the project where the poster is currently working are protected against corrosion using a specially enhanced, modified thick-gel epoxy coating. When using an electric spark leak detector, it makes a sound when testing that area; however, no sound is heard when testing the same area again. The poster is seeking advice from fellow users to understand what’s going on. The coating thickness, as measured by a thickness gauge, was found to be at least 800 microns, meeting the requirements.
The voltage is slightly increased; the spark generated by the electric arc isn’t long enough
Thank you, I’ll give it a try tomorrow:handshake

The voltage should be slightly higher (too high a voltage can damage the coating); if no alarm is triggered, it indicates that the coating is safe. This indicates that the previous alarms were caused by things like iron ash on the surface of the coating.
Thank you to the professionals for their answers: handshake
