Apparatus for cleaning the exterior of a pipe

An apparatus for cleaning the exterior of a pipe;

• comprising:
• a) a frame adapted to be mounted on a pipe to be cleaned;
• b) means operably associated with said frame for supporting said frame for movement on the pipe to be cleaned;
• c) at least a first endless flexible cleaning member extending around said pipe and adapted to directly engage a surface of the pipe;
• and,
• d) drive means operably associated with said frame for moving said endless flexible cleaning member relative to said frame for cleaning an exterior surface of the pipe, said endless flexible cleaning member extending in a first plane, said first plane extending substantially perpendicular to a longitudinal axis of the pipe to be cleaned.

An apparatus for cleaning the exterior of a pipe;

• comprising:
• a) a frame adapted to be mounted on a pipe to be cleaned, said frame having upper, lower, front and rear portions;
• b) a first roller being disposed adjacent said front portion of said frame for supporting said frame for movement along the pipe to be cleaned, a second roller being disposed adjacent said rear portion of said frame for supporting the frame for movement along the pipe to be cleaned;
• c) drive means operably associated with one of said first and second rollers for automatically moving said frame along the pipe to be cleaned;
• and
• d) a first endless flexible cleaning member extending around said pipe and adapted to directly engage a surface of the pipe and a drive operably associated with said frame for moving said endless flexible member relative to said frame for cleaning an exterior surface of the pipe to be cleaned.

• comprising:
• a) a frame adapted to be mounted on a pipe to be cleaned;
• b) means operably associated with said frame for supporting said frame on the pipe to be cleaned;
• and,
• c) a first endless flexible chain extending around said pipe and adapted to engage an exterior surface of the pipe and a drive operably associated with said frame for moving said endless flexible chain relative to said frame for cleaning only exterior surfaces of the pipe to be cleaned.

• comprising:
• a) a frame adapted to be mounted on a pipe to be cleaned;
• b) means operably associated with said frame for supporting said frame on the pipe to be cleaned;
• and,
• c) an endless flexible cleaning member extending around said pipe and adapted to directly engage the pipe and a drive means operably associated with said frame for moving said endless flexible cleaning member relative to said frame for cleaning the pipe, said endless flexible member forms a first loop which extends above and below the pipe to be cleaned.
