Abstract
The method of using the flow within a pipeline to clean the inner wall of the pipeline including placing the cleaning pig into the pipeline to be cleaned at a first location, using a restraining rope or cable to cause the cleaning pig to move along the pipeline at a speed slower than the speed of the flow within the pipeline and thereby causing a pressure differential between the upstream side and the downstream side of the cleaning pig, providing one or more jetting nozzles and using the pressure differential to jet a portion of the flow within the pipeline through the one or more jetting nozzles onto the inner wall of the pipeline while providing a flow area through the cleaning pig to bypass the portion of the flow which does not pass through the one or more jetting nozzles.
