FIELD: technological processes.
SUBSTANCE: invention relates to cleaning of internal surface of heat exchanger pipes from various contaminants. Method for cleaning the inner surface of pipes of heat exchangers, including supplying them with a non-laminar flow of a washing liquid for cleaning from deposits, at that, at the inlet and outlet of the pipes, a pressure difference is created, which provides a reverse flow of the washing liquid with a rate, providing turbulent flow, accelerating cleaning from deposits of inner surface of pipes without destruction of pipes and their connections.
EFFECT: higher efficiency of cleaning of pipes internal surface.
