The role of missed-coating inspection
Thread Content
Hello everyone, under what circumstances is it necessary to conduct a holiday test? Our factory has a LPG storage tank. There is usually no air/oxygen inside. Recently, the tank underwent regular maintenance, and the propane and butane inside were also emptied. The water pressure, airtightness, and magnetic particle testing were tested on it again. For the magnetic particle testing, it was necessary to remove the coating from inside the cylinder. Is there a need to check for missed coatings before operation? Thank you
