Leakage accidents in oil transmission pipelines not only cause loss of material, but also bring about hidden troubles for people's property and the environment. Pipeline leakage accidents occur frequently in recent years, particularly in those…
As negative pressure wave is applied to leak detection and location of natural gas pipeline, the key is how to realize accurate measurement of propagation velocity of pressure wave and time difference. However, there exists problem of lower accuracy…
This paper analyzes the properties of wavelet transform and its potential application in detecting the leakage location of gas pipeline. An entity-part method, which is proposed for the accurate leaking point, has been proved valid in the stimulation…
This paper presents an effective decision making system for leak detection based on multiple generalized linear models and clustering techniques. The training data for the proposed decision system is obtained by setting up an experimental pipeline…
The leakage detection system based on negative pressure wave method has been widely applied to crude oil pipelines. Aiming at its shortcomings in reducing false alarms and improving location precision, a combined Kalman filter - discrete wavelet…
