| Abstract: | The examination of leakage plays an important role in the safe operation of long oil pipelines. In this paper, the total design of a kind of oil transport pipeline based on the double parameter of pressure and flow is described. In pressure detection, it adopts the method of negative pressure wave, in which the theory of wavelet transform is used to catch the singular point of negative pressure wave. The solution is proposed to the determination of time and negative pressure wave velocity. This method may improve the leakage detection sensitivity and location precision. |
