This paper explored the possibility of using the AC FSM for internal corrosion inspection of pipeline without destruction. Principle analysis and numerical simulations were used to gain an insight into the AC current distribution in the material and to improve the probes configuration that installed on the outside surface of pipeline. The experimental setup for monitoring based on AC FSM was carried out, the main advantage of which is the currents injected are much smaller over existing commercial systems, the corresponding system security improved. At last, the applications showed that AC FSM system can successfully inspect the defects in the pipelines.
