Abstract
A pipeline treating apparatus (600) is disclosed which has a pair of pivotally mounted housing sections (604,608) and a pair of separately pivotal nozzle frames (610, 612). A nozzle plate is mounted on each of the nozzle frames and carries a plurality of nozzles (622). A drive mechanism on the nozzle frames oscillates the nozzle plate a predetermined arcuate distance around the circumference of the pipeline so that the nozzles treat the entire outer surface of the pipeline. The housing sections and nozzle frames are separately pivotal from a removal position, to allow removal of an installation of the apparatus on the pipeline, to a operational position concentric about the pipeline for performing the treating operation.
