  • Patent number: 6723266
    Abstract: A method and apparatus for making a pipe liner and the pipe liner itself. A thin walled pipe liner, after being provided cooled from a spool or extruded in tubular form and cooled, is deformed to a smaller cross section at ambient temperature. The pipe liner is then encased and held in its reduced cross section deformed shape by a protective sleeve which is co-extruded directly over the pipe liner. The sleeved pipe liner may then be wound on a drum for transport to a remote location. Ducts for water may pass through the pipe liner. Other ducts, for example, for fiber optics, may pass through the sleeve either within or outside of the deformed pipe liner.
