  • Method for repairing and strengthening pipe with internal helically wound tensile reinforcement
    Patent number: 8678043
    Abstract: A method for repairing and strengthening pipes by creating a structural reinforced composite liner within the existing pipe. The liner is created by helically winding a tensile reinforcement material on the inside wall of a pipe and encapsulating it in a hardening matrix material. The reinforcement material is helically wound around the inside wall of the pipe by an installation device. The installation device is configured to relieve and/or prevent the development of torsional stress in the reinforcement material that is created by the act of helically winding it onto the inside wall of a pipe, allowing the reinforcement material to lay flat against the pipe wall without twisting or buckling. The structural reinforced composite can be configured to supplement the strength of the existing pipe or to function as a stand-alone pipe within the existing pipe.
