Abstract
Apparatus and methods for lining a pipe line having a first pipe section in communication with a second pipe section where the first pipe section has an inside diameter greater than an inside diameter of the second pipe section. A transition tube having an outside diameter substantially equal to the inside diameter of the second pipe section and a length substantially equal to or greater than the length of the first pipe section is inverted into the pipe line along with a liner. A resinous material applied to the liner cures and hardens the liner after inversion. The transition tube creates a surface against which the liner can be compressed to help prevent the liner from being overstretched in the wider first pipe section.
