FIELD: process engineering.
SUBSTANCE: proposed device comprises jet collar fitted in cylinder plugged at rear end. Collar, cylinder and face cover make water intake chamber for water to wash away sediments through collar conical slits. Pipeline is cleaned by jets that create cylindrical layer parallel with pipeline. Jets move toward pipe walls and along the pipe to wash away sediments into well or slime pit. Device is towed by cable to clean the pipe and to gage pipe channel. Besides, proposed device comprises outhaul cable.
EFFECT: higher efficiency of cleaning.
