FIELD: cleaning inner surfaces of water supply pipes, thermal and road network, reclamation systems.
SUBSTANCE: proposed device has body in form of hollow elastic cylindrical envelope which is deformable under action of working medium fed to it under pressure. Cleaning unit is made in form of many metal teeth mounted at angle relative to envelope surface; direction of inclination of teeth coincides with direction of motion of device in the course of cleaning. Device may be used for pipes of different sizes whose diameters range from 1.1 to 1.6 of diameter of envelope in initial state.
EFFECT: increased productivity; improved quality of cleaning due to applying proportioned pressure of teeth on pipe line walls.
