Abstract
The plug installation apparatus comprises a mechanism for moving an internally captured expander member relative to the shell wherein it is captured thereby expanding the plug into contact with the internal surface of a tube within which the plug is disposed. The apparatus further comprises a sensor mechanism for determining that the plug has been properly inserted in the tube prior to expanding the plug for preventing improper expansion of the plug. The apparatus also comprises force measuring devices for determining and verifying that the proper amount of force has been applied to the expander member.
