Abstract

See full text

A method and apparatus for exhausting steam in steam curing a cured-in-place liner that avoids directing the steam toward a house or building in communication with a pipeline in need of repair. One embodiment includes the use of a liner, a bladder, and an exhaust hose operatively connected to the bladder. A resinous material capable of curing and hardening is applied to the liner. The bladder presses the liner against the pipeline. The end of the steam exhaust hose connected to the bladder is positioned on the interior of the bladder and the opposite end of the steam house is positioned outside the bladder to direct steam away from the house or building as steam is introduced inside the bladder to assist in curing the resinous material.
