Abstract

Apparatus for the cleaning of the exterior surface of a pipeline or the like includes a frame defining a longitudinal passage of a size sufficient to permit the pipeline to extend longitudinally therethrough. A first cleaning unit and a second cleaning unit are mounted on the frame. Each cleaning unit includes a plurality of jet modules. In turn, each jet module includes a rotatable jet nozzle mounted to deliver a jet of cleaning liquid toward the pipeline exterior surface. A high pressure cleaning liquid source is also provided and is connected to the rotatable jet nozzles to provide high pressure cleaning liquid to the nozzles.
