ABSTRACT:
An apparatus for inserting a lining material into a pipeline includes an elongated carrier device having a hollow central portion which encloses a liner-bladder assembly. The liner-bladder assembly includes an elongated inflation bladder which engages an open end of the carrier device and expands under fluid pressure out of the carrier device. The pipe liner is frangibly attached to the inflation bladder such that its attachment anchors the liner with respect to the open end of the carrier device to permit accurate placement of the liner within a pipeline proximate to a compromised section of the pipeline. The frangible connection breaks when the carrier device and inflation bladder are removed from the pipeline.
