FIELD: cleaning facilities. SUBSTANCE: invention relates to machines for cleaning surfaces of pipes from old insulation and dirt and for cleaning circumferential and longitudinal seams. It solves the problem of continuous displacement of cleaning tools along axis of cleaned pipeline. Proposed machine consists of framework with two sides on running wheels. Framework accommodates chain drive of tool carrier made in form of flexible hoop consisting of hinge-secured U-shaped sections with teeth for chain on outer surface. Section accommodate supper rollers whose axes are located at angle relative to longitudinal axis of hoop. Rotation of hoop along screw line is provided, i. e. its travel along axis of pipeline. Ends of hoop and ends of drive chain are connected without tools. EFFECT: reduced time taken for mounting and demounting of machine on pipeline to be repaired. 5 dwg
