Cleaning inside of pipes to remove deposits on walls - using high pressure water jets with ultrasonic lamellar flow to dislodge internal coating which is carried away by water

摘要

The cleaning process uses high pressure jets of water with lamellar flow creating in-situ ultrasonic vibrations. The water is injected at a pressure of more than 600 bar, emerging with lamellar jets having a speed of more than 1,450 m/sec. The jets are injected into the pipe in a direction opposite the normal direction of flow of liquid in the pipe. The high pressure water jets dislodge the coating inside the pipe and the water flow carries the waste away for collection at the end of the pipe.
