1. A method of conduit reparation including an existing, host conduit and a tubular target conduit formed from a rigid, thermoplastic material, the method comprising:
providing injection hardware in operative communication with an injection end of at least one of the host conduit and the target conduit; providing distal end hardware in operative communication with a distal end of at least one of the host conduit and the target conduit; providing a control mechanism in communication with at least one of the injection hardware and the distal end hardware, the control mechanism configured to at least one of communicate with and control at least one of the following: the conduit reparation process, the injection hardware, the distal end hardware or any combination thereof; positioning the target conduit having a first diameter within the host conduit while maintaining the target conduit in a rigid state; expanding the target conduit by injecting a heated, pressurized gas or liquid material directly into an inner area of the target conduit, such that the temperature and pressure of the gas or liquid cause the target conduit to expand to a second, larger diameter resulting in a structural, expanded target conduit, the heated, pressurized gas or liquid material is at least one of injected through the injection hardware to provide injected material and recycled from the injection hardware to provide recycled material; and controlling, by the control mechanism, at least one of the following: the temperature, pressure, volume or any combination thereof, of the heated, pressurized gas or liquid. |
