ABSTRACT:
Apparatus for brush-cleaning the interiors of pipes, wherein rotative brushes are carried by a rotative carrier plate. The brushes are rotated by air motors, and rotate at very high speeds. The brushes are spring-loaded to consistently bear against the inside of the pipe wall, and are disposed at a small angle from radial which results in reduced brush wear and more efficient pipe wall cleaning.
