A system for curing a pipeline liner that includes a resin curable by exposure to radiation includes first and second liner curing apparatuses, each of which includes a housing defining opposite first and second ends, and outer and inner walls defining a passage between the first and second ends; a plurality of LED's on the outer wall and operable to irradiate the radiation; and a plurality of heat dissipating elements on the inner wall. The LED's are connected in thermally-conductive relationship to the heat dissipating elements, whereby heat is dissipated from the heat dissipating elements to cool the LED's when a stream of cooling fluid passes through the passage. In use, the apparatuses, joined end-to-end, are moved within the liner while irradiating radiation from the LED's onto the liner, and the velocity of the apparatuses moving through the liner is adjusted to cause a complete curing of the resin. |
