Leak locating microphone

Patent Pending Pipeline leak detection includes hydrostatic test after pipeline erection and leak detection during service. This article mainly refers to in-service leak detection. Pipeline networks are the most economic and safest mode of transportation for oil, gases and other fluid products. As a means of long-distance transport, pipelines have to fulfill high demands of safety, reliability and efficiency. If properly maintained, pipelines can last indefinitely without leaks. Most significant leaks that do occur are caused by damage from nearby excavation equipment, therefore it is critical to call authorities prior to excavation to assure that there are no buried pipelines in the vicinity.
