A method for installing a tube repair sleeve in a tube at a selected location relative to a tube defect or a tube support. The method includes using a hydraulic expander having at least one expandable bladder. The expander includes a stud having at least one conduit formed therein and a plurality of slidable expandable bladders mounted on the stud for radial expansion, each of the bladders in fluid communication with the conduit. A detector means is mounted on the expander and responsive to tube supports and defects in the tube. Finally, a control system is electrically connected with the detector means and operative to control the expansion of the bladder in response to signals received from the detector means.
