Abstract
In a pipeline lining method, a tubular lining material impregnated with a thermosetting resin is inserted in an everted state into a pipeline and expanded and pressed against an inner peripheral surface of the pipeline. A vapor mist and water at normal temperature are sprayed toward the tubular lining material and mixed together to cool the vapor mist. The cooled vapor mist is directed onto the tubular lining material to cure the thermosetting resin impregnated in the tubular lining material to line the pipeline with the tubular lining material.
