The possibilities of using characteristics of special-correlation analysis as informative parameters for the acoustic-emission (AE) inspection of pig launchers-receivers (PLRs) of oil main pipelines (OMPs) are considered. The acoustic emission caused by wind and atmospheric precipitation that act on a pipe and, thus, generate noise are studied. It can be concluded from the preliminary analysis that the effective width and median frequency of a spectrum can be used to identify the AE inspection processes of PLRs of OMPs.
