ABSTRACT:
A machine for remotely lining the inside of a heat exchanger tube end (13) received in a tube plate (14). The machine includes a flexible tube (15) connecting a push-pull device to a motorized unit (16) for driving tools used for fixing the sleeve in the heat exchanger tube. The machine also includes a tool loader (25, 26) at the head of a cable (20) which is driven by the push-pull device and means for applying the end of the flexible tube to the end of any of the heat exchanger tubes which may need lining. The motorized unit (16) includes two superposed fluted hubs (30, 33) one of which is driven by a low speed electric motor while the other is driven by a high-speed pneumatic motor.
