In this paper, the steel pipe was corroded by electric chemistry. The piezoelectric ceramic sensor was placed on the normal surface and the corrosion surface respectively. The active induction method of the piezoelectric ceramic sensor was used to detect the steel pipe with different corrosion degrees. The results show that the greater the degree of corrosion of the steel pipe, the smaller the signal voltage value received by the piezoelectric ceramic sensor, and the greater the damage index. The active induction method can be used to detect the damage change of the corrosion of the steel pipe through the piezoelectric ceramic sensor.
