METHOD AND SYSTEM FOR ASSESSMENT OF PIPELINE CONDITION BY GENERATING A PLURALITY OF PRESSURE WAVES AND DETECTING THE INTERACTION SIGNAL FROM A LOCALISED VARIATION AND COMPARING THE ACTUAL SIGNAL TO A PREDICTED DATA MODEL
591739 Disclosed is a method for assessing the extent and location of localised variations in pipe condition, corrosion, elastic stiffness, thickness, or internal cross sectional area of the pipe wall along a length of a pipe carrying a fluid or liquid. The method includes the steps of generating a pressure wave in the fluid being carried along the pipe and detecting a pressure wave interaction signal resulting from an interaction of the pressure wave with localised variations in pipe condition along a length of the pipe. The timing of the pressure wave interaction signals determines the locations of the localised variations in pipe condition, and the extent of the localised variation in pipe condition is determined based on a change in the magnitude of the pressure wave interaction signal.
