Investigation on a reliable leak detection system for oil & gas pipeline
Based on the theory of negative wave, the experiment equipment of pipes leak detection is rebuild, which compose of examination loop pipe, signal inspect system and assistant system. For negative pressure cause by leak will transmit in pipeline and make the pressure drop at once, the collection pressure signal is calculated by wavelet algorithm and the different time negative pressure transmit between first inspection point and last inspection point can be calculated based on the theory of wavelet algorithms model max value always corresponding the signals oddity point. The experiment data was used to take as example at the software MATLAB6.1. In the course of calculation, Haar wavelet was selected as base wavelet and level was 6. The result indicates its effect and make a base for the accurate leak detection and find leak point precisely.
