Abstract:
A system and method for repairing and reinforcing a pipeline includes a pair of opposing composite wrap bands that are located on the external surface of the pipeline and positioned a predetermined horizontal distance from a defect area. A composite wrap is then applied over the bands to create a bridge that spans the bands and forms a cavity above the defect area. The bridge eliminates the need to clean the surface of the pipeline directly over the defect area. A second pair of bands located on the external surface of the bridge provides structural support. An actuator within the bridge monitors the pressure within the cavity and activates upon the presence of internal pressure, indicating a through-wall defect has occurred. A fitting may also be inserted into the bridge in order to pressurize the cavity and test the repair.
