ABSTRACT:
Apparatus for processing the damaged tubes of a steam generator either to prepare the tubes for insertion of a sleeve, or to insert a sleeve or to treat the sleeve after it is inserted. This apparatus includes a drilling tool for drilling out plugs, a sleeving tool for inserting sleeves in the tubes, a high-roller tool for rolling the sleeves at their upper ends where they have been expanded, and a low-roller tool for rolling the sleeves at their lower ends in the tube sheet. The sleeves are inserted in the tubes and are rolled by rolls driven by a hydraulic motor. For drilling, for sleeve insertion and for high and low rolling, the motor is controlled by a servo control valve.
