The field signature method (FSM) is a nondestructive testing (NDT) method based on the potential drop (PD) technique and has been applied to online metal pipe corrosion monitoring for nearly three decades. The many advantages and benefits of the method have been reported in a number of studies, but few have reported on its limitations or shortcomings. However, the detection accuracy for pitting corrosion...
Field signature method (FSM) is based on a potential drop (PD) technique and has been applied for nearly three decades for online metal pipe corrosion monitoring in many industrial areas. However, the detection precision of FSM for localized corrosion is still very low because the current field distribution in the measured pipe will be changed during the corrosion process but the formula used to assess...
