Leak Detection Methods in Transmission Pipelines

Abstract

Leak detection in transmission pipelines is important for the safe operation of pipelines. The probability of leaks may occur at any time and location, therefore, pipeline leak detection systems play a key role in minimization of the occurrence of leaks probability and their impacts. Today, there are many available assortments of modern technologies in the domain of leak detection. This article provides the proper methodology to facilitate the choice of leak-detection system. The article deals with external methods based on external measurements, such as acoustic emissions, cable sensors, liquid sensing, and vapor sensing, and with some internal methods based on flow and pressure measurements in the pipeline; volume or mass balance method, pressure wave detection method, and analytical method were described. Additionally, the discussion of error sources and final conclusions are presented.
