FIELD: heat supplying systems, sewerage pipes, central heating radiators. SUBSTANCE: method includes generation of shock waves in a fluid by supplying pulses of air under high pressure. The shock wave is generated close to the inlet of the pipe-line in a hydraulic unit which also provides filling the pipe-line with fluid and discharging contaminations in one closed cycle. The device contains air-operated ram provided with a source of compressed air and cross- shaped hydraulic unit. One pair of the unit branch-pipes is connected to the air- operated ram and pipe-line. The second pair is connected with the source of fluid and drain tank. The air-operated unit provides the following alternative connections: air-operated ram-pipe lined; fluid-pipe-line; pipe-line - drain tank. The branch-pipe connecting with the pipe line contains a flanged nut provided with adapter for connecting with pipes of various diameters. Other branch-pipes are provided with ball valves. EFFECT: enhanced efficiency and reliability. 3 cl, 3 dwg
