Abstract
The present invention provides apparatus, including a pigging tool, that comprises a spraying mechanism configured to move along an inner surface of a pipeline, including a slurry transport pipeline in a minable oilsands facility or plant, and to spray a coating on the inner surface of the pipeline; and a curing source, including an ultraviolet (UV) light source, a microwave source or an RF source, configured to cure the coating sprayed on the inner surface of the pipeline in situ as the spray mechanism moves along the inner surface of the pipeline.
