It is well known that corrosion drastically shortens the lifespan of pipelines. Pipe wall thinning and leakage due to corrosion are important safety concerns for pipes used in oil, petrochemical, and power plant industries. Cross-sectional…

The defect classification is investigated by using features-based giant-magnetoresistive pulsed eddy current (GMR-PEC) sensor. The power spectrum density of the intrinsic mode functions (IMFs) is extracted as the classification feature, considering…
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)…
