摘要

Lining pipe comprises a fiber strip impregnated with at least one epoxy resin, where the epoxy resin is a epoxy resin, which is curable by photochemically initiated cationic polymerization process. An independent claim is included for the renovation of piping systems comprising inserting the liner bag impregnated into the epoxy resin into a portion of the pipeline system to be repaired, expanding the lining bag tube to an inner wall of the piping system, which is in the operating condition of the piping system in contact with the transported medium in the piping system, and irradiating the lining bag with an electromagnetic radiation with a wavelength, which is suitable for curing the epoxy resin.
