ABSTRACT:
An improved method of inserting a liner into a metallic pipeline is disclosed. The liner is formed from a plurality of concentric tubes that are enveloped in a flexible, expansible, tear resistant material. When the concentric tubes are pulled into the pipeline, the tear resistant material provides protection against tearing of the tubes by burrs, snags or other imperfections on the inside of the metallic pipeline. The tear resistant material may be a fabric, woven material or mesh. Materials having a structure that permits escape of fluid entrapped during subsequent expansion of the concentric tubes on formation of the liner are preferred. The method permits the lining of pipeline sections that have bends, loops or the like, while protecting the liner from tearing during insertion into the pipeline.
