11 48,879 ABSTRACT OF THE DISCLOSURE The plug removal apparatus comprises a ram mounted in a rod both of which are mounted in an activat- ing cylinder. The rod is capable of being screwed into the plug such that when the cylinder is activated, the cylinder causes the ram to push the expander relative to the plug while the rod holds the plug thereby relieving the pressure on the plug. The activating cylinder may then be activated so as to extract the plug from the tube using short strokes. The apparatus is capable of being used manually or remotely so as to be able to remove plugs from heat exchangers and nuclear steam generators.
