Method For Detecting Defects In A Tube Heat Exchanger

A method for maintaining a tube heat exchanger includes:obtaining measurement signals resulting from the passage of a measurement probe in the tubes of the heat exchanger,determining a reference time series corresponding to an average, at each instant, of the measurement signals,synchronising each m...

Zusammenfassung:	A method for maintaining a tube heat exchanger includes:obtaining measurement signals resulting from the passage of a measurement probe in the tubes of the heat exchanger,determining a reference time series corresponding to an average, at each instant, of the measurement signals,synchronising each measurement signal with the reference time series by applying a dynamic time warping, DTW, to said measurement signal and the reference time series, andsearching for a potential anomaly by measuring a potential local deviation of a measurement signal with respect to the other measurement signals.
