Finding Leaking tubes in heat exchangers
When there is suspicion a tube or tubes are leaking in either oil coolers, condensers, heat exchangers or boilers. Two men work together or one with a sealing plug work together on the same tube. The one with the sealing wand places it in the tube and the other operator places the test unit in the same tube and once operated a vacuum is produced in the tube. If the tube maintains its vacuum then the tube has no leaks, a decreasing vacuum gauge verifys a leaking tube.
Consult the PDF Specifications below to cross refer all data to the tube OD, wall thickness and tube sheet thickness. Also, part numbers for spare mandrels and rollers can be found here. If the PDF is two pages then the data has to be read across the two pages.
