FIELD: process engineering.
SUBSTANCE: invention relates to operation of pipeline systems, particularly, to cleaning pipeline inner surface and may be used for cleaning pipeline inner space of bitumen-gummy deposition. Piston made from elastic synthetic material represents a cast hollow cylinder with head. Cylinder outer surface has one or several annular stepped ledges. Through holes are made ahead of said ledges to penetrate into piston inner space, the number and sizes of said holes being subject to pipeline diametre. Given more than one ledges on cylinder surface, ledge diametre increases from cylinder head to face. Note here that the last ledge or several ledges from cylinder head feature diametre equal to or exceeding pipeline ID.
EFFECT: higher quality of cleaning, ruling out of pipeline plugging.
