METHOD USING TEST LIQUID AND ULTRASONIC LEAK DETECTOR FOR DETECTING LEAKS IN PIPELINES

摘要

A method for detecting leaks in pipelines that is sensitive to acoustic signals in the ultrasonic range with the detector being transported through the pipeline by fluid flow. The method comprises transporting the detector through the pipeline while maintaining the detector in a test liquid having a viscosity of 30 cS maximum and a Reid vapor pressure of 10 psi maximum while recording the ultrasonic noise level.
