PROCESS FOR THE PRODUCTION OF A PIPE LINED WITH AN INLINER

The method involves introducing a thermoplastic inliner into an interior of a carrier pipe. An outer side of the carrier pipe is heated to temperature higher than a crystallite melting point (Tm) of a molding composition of an exterior surface of the inliner. The inliner in the carrier pipe is expan...

Zusammenfassung:The method involves introducing a thermoplastic inliner into an interior of a carrier pipe. An outer side of the carrier pipe is heated to temperature higher than a crystallite melting point (Tm) of a molding composition of an exterior surface of the inliner. The inliner in the carrier pipe is expanded radially such that the heated exterior surface of the inliner assumes the shape of an interior surface of the carrier pipe. The inliner is cooled.
