Vibration Diagnostics of Gas Pipelines Technological Equipment Using Wavelet Analysis

This paper dwells upon the methods for diagnosing ground gas pipelines as a part of gas-compressor station equipment. Such methods were used in accordance with normative certification documents. A supposition was made that the design of such pipelines had several faults. This paper is devoted to the methods of diagnosing entire gas pipelines or parts thereof for such faults during expert inspection and certification protocol registration. The analysis of all defects allows determining the time-between-repairs so as to develop some operations for the purpose of avoiding these faults, evaluating the repair operation quality and reducing failure probability.
