Pipeline systems are a safe method of transporting oil and gas from one place to another, although they suffer from leaks due to external and internal factors and fail to deliver the required products to customers. Many methods have been researched…

In this paper, an algorithm for gas pipeline leak detection based on Hilbert-Huang transform(HHT) studied. And both Fourier transform and HHT transform can be used to decompose pipeline leakage signals. The results that Fast Fourier Transform(FFT)…
A new time-frequency analysis method of Hilbert-Huang transform applied in Pipeline leak detection is proposed. Choosing the negative pressure wave signal from dynamic pressure transmitter as research object, the dynamic pressure signal is decomposed…
