- Abstract:
- A detection method that could integrat field signature method (FSM) and electromagnetic ultrasonic transducer (EMAT) was proposed,aiming at the problem that the online monitoring data of metal pipe corrosion in the petrochemical industry was not reliable. Through the theoretical analysis of the measurement principle of FSM technology, the source of data error in the measurement process was identified, that was, the expression of offset voltage. The measurement results of FSM were compared with the measurement results of EMAT, and the measurement data of EMAT at a certain moment was taken as the true value of FSM data to obtain the corrected probe voltage value. Thus, the problem of data drift caused by zero offset voltage and data processing unit magnification change during long-term measurement was corrected, and the large-scale and long-term stable online monitoring of pipeline was realized. The experimental results showed that after two years of practical application, the proposed method could reduce the maximum error of FSM measurement data from 10.09% to 0.49%, and the maximum error was reduced by 9.6 percentage points.
