PLUG REMOVAL APPARATUS

摘要

A plug handling apparatus comprises a ram (32) mounted in a rod (12) both of which are mounted in an activating cylinder (14). The rod (12) is capable of being attached to the plug (68) such that when the cylinder (14) is activated, the cylinder (14) causes the ram (32) to push an expander into the plug (68) while the rod (12) holds the plug (68) thereby relieving the pressure on the plug (68). The activating cylinder (14) may then be activated so as to extract the plug (68) using short strokes. The apparatus is capable of being used manually or remotely for the removal of plugs from heat exchangers and nuclear steam generators.
