ABSTRACT:
A repair device and method for its use includes plugs that pressure isolate an internally damaged pipeline section and an hermetically sealed housing that contains a length of composite material and a means for controllably releasing the composite material. In a preferred embodiment, the composite material is a pre-cured composite plank and the releasing means is a rotatable carriage assembly. The carriage assembly includes pairs of rollers that maintain the composite material in its coiled state and provide for its controlled release onto the interior wall of the pipeline. The carriage assembly also includes a nozzle for injecting an adhesive into a roller. The roller applies the adhesive onto the interior wall surface and then presses the composite material into the adhesive as the carriage assembly rotates and the composite material uncoils. A pneumatic or electric motor may be used to power the carriage assembly.
