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.

Device for surface cleaning, surface preparation and coating applications

A direct drive motor and swivel assembly is provided. The assembly comprises a motor with a modified motor shaft extending through the motor. The motor shaft has a longitudinal passageway extending therethrough and a first end which is disposed outside of the motor and a second end opposite thereto. The swivel shaft of a swivel is axially aligned with the first end of the motor shaft and coupled thereto at a point outside of the motor such that the motor shaft passageway and swivel shaft passageway are in communication. The second end of the motor shaft may be connected to nozzles such that fluid flowing through the swivel housing into the swivel shaft and motor shaft will exit the second end of the motor shaft and flow through nozzles.
