Development of methods of detection of pipelines corrosion defeat by computer modeling

Corrosion defeat of metal is one of the most widespread defects arising at operation of the pipeline transport systems. Deep corrosion of pipe surfaces leads to developing fistulas and losses of the transported product. In relation to systems of heat supply, leaks even through small discontinuities lead to considerable losses of thermal energy and heat carrier within a year. The purpose of work is development of a technique of detection of corrosion defeat of pipelines by an acoustic method. For effective detection of corrosion defects, it is necessary to determine informative ranges of frequencies by the analysis of acoustic signals.
