Abstract: A coating system to coat the interior of a pipeline section using a UV curable coating and an internally pressurized UV foil that assists in suspending and distributing coatings during UV curing. The UV foil may be installed through the length of the pipeline section using an inversion system driven by pressurized air. The system includes a coating delivery system for distributing the coating along the interior of the pipe. The system includes a UV light source capable of delivery sufficient UV light to cure the coating. The UV light source may include a light train having a plurality of UV light sources, such as UV light emitting diodes, carried by a motorized trolley. The coating system includes an inlet adapter that facilitates inversion and pressurization of the UV foil, as well as introduction of the UV light source into the interior of the pressurized UV foil.
