The Semipermeable Technology on Natural Gas Pipeline Leak Detection

As a clean and efficient energy, natural gas is increasingly noticed at home and abroad. Pipeline being the major means to transmit natural gas, its operation safety is particularly important because of the inflammable and explosive characteristics of natural gas. This paper proposes a method of extracting leakage gas directly and testing using semi-penetration pipe and realizing real-time on-line inspection and positioning of the pipeline leakage; and it analyzes the profound importance of the leak detection technology as the construction of the gas pipeline network is rapidly developing; and it also analyzes and evaluates the leak detection technology in recent years at home and abroad, and it eventually succeeds in working out the rationality and adaptability of this leak detection method.
