Hole detection of Drilling Pipe with resistance of 40000 ohms
04 February 2019
How you can check the pin hole of coating using wet sponge gauge at a voltage rating of 67.5 Volts with new drilling pipe resistance of 80000 ohms and old drilling pipe resistance of 40000 ohms?
What is the different method for two different resistance?
