Improving the diagnostic model of municipal pipe-line for increasing the leakage detection reliability

Acoustic bulletin, Vol. 8 ¹ 3, (2005) p.3-16
The paper deals with increasing reliability of leakage detection for underground municipal heat supply systems by the correlation leakage indicators. A diagnostic model of the pipe-line corresponding to operation algorithms and and techniques of leakage indicator use is analyzed. The results of leakage detection, which cannot be explained within this model, are shown. The results of the experiments intended for discovering the diagnostically significant features of acoustic wave propagation in the pipe-lines are presented. The diagnostic model of the pipe-line is improved on the basis of these data and practical results concerning its use for increasing the leakage detection reliability are presented.
