Abstract: Analyzed the technical problem of providing resource details of fuel equipment and systems natural gas transportation, taking into account their contamination in the manufacturing process and operation. Shown promising application for the removal of contaminants by ultrasonic cleaning method. It was noted that this method is a classic application has limitations on the quality removal of contaminants from the internal cavities and channels in which the intensity of cavitation processes is reduced. Proposed, theoretically substantiated and experimentally confirmed method of increasing up to 10 times the effectiveness of ultrasonic cleaning of these surfaces by the product of ultrasonic vibrations directly in the area of localization of contamination.
