3PE anti-corrosion steel pipe spark detection
Sep 29,2024
After the 3PE anti-corrosion construction is completed, in order to ensure the quality of the external anti-corrosion of the 3PE anti-corrosion steel pipe, an electric spark test must be carried out, and a professional electric spark tester is generally used.
Connect one end of the red wire of the detector to the rubber rubbing electrode (the rubber probe has good contact with the anti-corrosion layer of the tested pipeline), and the other end to the high-voltage output (+) terminal (white) at the back of the instrument. Connect one end of the black fish clip wire to the anti-corrosion conductor of the tested pipeline, and the other end to the grounding terminal (black) at the back of the instrument. Insert the 220V power cord into the 220V input socket, turn on the power switch of the instrument, the LCD display shows the output high voltage value, the working indicator light is on, and the instrument is in working condition.
The 3PE external anti-corrosion detection can reach up to 25,000 volts.
