ABSTRACT:
Apparatus mountable on a pipeline for cleaning the outer surfaces thereof having a self-propelled carriage for travelling axially on the pipeline. The carriage transports two annular casings that are hollow and within each is housed a chain rotor driven rotationally therein as the carriage travels axially on the pipeline. The casings and rotors each have an upper half-ring and a split lower half-ring. As the lower half rings of the casings are opened and closed the chain rotors are opened and closed and the pitch thereof is retained. The casings and rotors therein are constructed so that the split half-rings can be opened sufficiently to pass the pipeline between distal ends of the split rings for allowing mounting and dismounting of the carriage on the pipeline.
