A process of reinforcing a thermoplastic pipe containing locating a thermoplastic pipe containing at least one defect on the outer surface extending at least partially into the pipe wall thickness. A tie-layer film is wrapped approximately one full rotation around the circumference of the pipe and energy is applied to the film, adhering the film to the outer surface of the pipe. An uncured reinforcing material containing a textile at least partially embedded into an uncured matrix is wrapped on the outer surface of the pipe at least one full rotation about the circumference of the pipe completely overlaying the defect. A machine is attached for reinforcing a thermoplastic pipe onto the thermoplastic pipe and energy is applied to cure the uncured matrix forming a cured reinforcing material. A machine for delivering the energy is also disclosed.
A machine for reinforcing a thermoplastic pipe, wherein the thermoplastic pipe has an outer surface and a length and at least one defect on the outer surface, wherein the machine comprises:
