Abstract
A method for applying a liner to a pipe is disclosed. The methodology includes inserting an apparatus within the pipe and moving the apparatus at a predetermined speed through the pipe. The method sprays a material from a spray head secured to the apparatus. The methodology also includes an oscillation system wherein the spray head assembly will move relative to the base assembly thus creating an over lapping pattern for the spray coating being applied to the interior surface of the pipeline. This oscillation system will allow for a more uniform coating to be applied.
