Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The bladder is stored in a pressure bladder canister coupled to a pressurized downtube and eversion elbow. The bladder is everted by introducing pressurized air into the canister As the bladder reaches the distal manhole, it enters a receiving canister where it is punctured while maintaining air pressure within the bladder a pinch valve between the downtube and elbow isolates the inverted bladder so that steam can be introduced into the bladder to cure the resin and exhaust through the receiving canister. The bladder is then removed and lateral service reinstated.

Abstract: An apparatus for installing a cured in place lateral seal in an existing main pipeline wherein the lateral seal includes a brim portion bonded to a short tubular portion.

Abstract: A method of lining an existing pipeline or passageway with a lining tube of a resin absorbent material impregnated with a curable synthetic resin is provided. A lining tube inserted into the pipeline and urged by pressure against the pipeline or passageway surface and heat is applied is stages to lengths of the lining tube by isolating a length of the uncured flexible lining from the remainder of the lining tube by expanding an expansible and contractible member inside the lining. A heated fluid medium is supplied to the isolated length so that the heat cures the resin within the isolated length. The contractible member is contracted and displaced along the length to isolate a new section of the lining tube which is then cured.
