Abstract
A rehabilitated pipe system and a method for rehabilitating a pipe system. A lines a host pipe and a coupling member configured for being operatively coupled to a mechanical coupler is positioned adjacent the host pipe so that a connecting section of the liner extends into the coupling member. The connecting section of the liner is adhesively bonded to the coupling member, and the mechanical coupler is installed to fluidly couple the liner to another fluid conducting structure. The connecting section of the liner can be formed in a portion of the host pipe that is removed after lining. The coupling member can be flanged or include a lateral coupling tube. The mechanical coupler can, e.g., be a ductile iron coupler or a bolt.
