Leak detection from liquid transmission pipelines using pressure wave technique — study of the use of two standard- and non-standard-measuring devices
Journal Title: Bulletin of the Military University of Technology - Year 2014, Vol 63, Issue 1
Abstract
This paper deals with leak detection in liquid transmission pipelines. Diagnostic method based on negative pressure wave detection is taken into account here. The paper focuses on variant of this method, related to the use of only two measurement points (devices), placed at the inlet and outlet of the pipeline. Standard transducers for measurement of pressure signals and non-standard elaborated technique for measurement of new diagnostic signals were used. New diagnostic signals, conventionally named the signals of weak interactions, result from the work of special devices (correctors) joined to the pipeline. In order to compare both hardware solutions key performance attributes for the analyzed leak detection method were determined. The bases of such assessment were experimental tests. They were conducted with the use of a physical model of a pipeline. The pipeline was 380 meters long, 34 mm in internal diameter and made of polyethylene (PEHD) pipes. The medium pumped through the pipeline was water. Carrying out such research, diagnostic procedures elaborated by the author were used and tested.[b]Keywords[/b]: technical diagnostics, pipelines, leak detection
