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.

Claim (Index 20):
An apparatus for repairing a portion of a single linear pipe having a first pipe section, a second pipe section, and a third pipe section, wherein the second pipe section has an inside diameter greater than an inside diameter of the first pipe section and greater than an inside diameter of the third pipe section, the apparatus comprising:\n a liner assembly comprising a liner tube having a first end; a transition tube having an outside diameter smaller than the inside diameter of the second pipe section and a length substantially equal to or greater than the length of the second pipe section, the transition tube being secured to the liner assembly a predetermined distance from the liner tube first end; wherein upon inversion of the transition tube and the liner tube into the second pipe section the transition tube is on the outside of the liner tube in the first pipe section and the liner tube extends beyond the transition tube and within the third pipe section.
