PLUGGING APPARATUS FOR HEAT EXCHANGER

摘要

The invention makes it possible to carry out in a remote-control and continuous manner the work of fixing a mechanical plug in a heat transfer tube of a steam generator or heat exchanger of a reactor. A plugging apparatus (50) for a heat exchanger comprises a main body (52) capable of being coupled to a tool guide robot movable inside a water chamber of the heat exchanger under remote control, a plug fixing mechanism (54) mounted on the main body for conveying a mechanical plug (5) from outside the heat exchanger and fixing the mechanical plug in the heat transfer tube (1), and a clamping mechanism (56) for clamping the main body to a tube plate of the heat exchanger at a desired position on the tube plate of the heat exchanger.
