FIELD: machine building.
SUBSTANCE: cleaning brush consists of case filling cross section of pipe by means of at least two collars positioned at distance from each other in lengthwise direction. The case moves forward in a specified direction together with fluid medium transported through a pipeline. The brush has at least one delivery orifice located on a back side. Through a pressure line the orifice leads to a draining orifice coming out in an interval between the collars and directed onto an internal wall of the pipeline.
EFFECT: cleaning brush implemented as common cleaning brush and transferred by means of transported substance of fluid medium; higher cleaning efficiency of brush at removal of specific deposits on pipe walls; reduced wear of brush in area of its collars.
