ABSTRACT:
The present invention relates to a device and method for lining a steel or iron service pipe with a plastic liner and securing an end of the plastic liner to the inside surface of the service pipe. More particularly, the device includes an expanding means removably attached to a hydraulic operated piston, and a plastic sleeve crimped to one end of the plastic liner. The piston forces the expander into the sleeve to deform the sleeve out against the service pipe.
