摘要
A method of in-situ pipeline replacement in which valves, fittings, and other obstructions are removed from an existing pipeline, a heat-fusible polymer pipeline having an initially deformed configuration less than the existing pipeline diameter is inserted into the remaining portions of the existing pipeline and reformed to substantially conform to the inside diameter of the existing pipeline, heat-fusible fittings are provided to replace removed portions of the existing pipeline and heat-fused to the polymer liner, and transition fittings provided to operably connect the replacement pipeline to those portions of the existing pipeline not within the replacement scope. The completed replacement polymer pipeline creates an operable wetted pressure boundary within the bounds of the replaced existing pipeline.
