ABSTRACT:
Apparatus for cleaning each threaded marginal end portion of large pipe. The apparatus has a cleaning head assembly which includes a rotatable member having circumferentially spaced cleaning brushes adjustably mounted thereon so that the cleaning brushes can engage and clean the opposed pipe surface at the opposed marginal terminal ends of a joint of pipe. Spaced plate-like members are axially arranged along a common shaft, and the opposed faces of the plate members have the cleaning brushes adjustably mounted thereto and arranged so that the common shaft can be rotated in a horizontal plane, thereby bringing the brushes of one of the plate members into cleaning engagement respective to the pipe threads, and thereafter the assembly is rotated 180.degree.0 in a horizontal plane, thereby bringing the other set of brushes into cleaning relationship respective to the opposed pipe end. In another preferred form of the invention, the cleaning apparatus is combined with a pipe protector remover apparatus, all of which is mounted to a main frame. The main frame can be moved vertically, laterally, and longitudinally respective to a pipe. The main frame is rotatable about a vertical axis so that either the protector remover or the cleaning apparatus can be brought into operative relationship respective to either end of a pipe.
