Abstract:

Corrosion of buried pipelines can lead to catastrophic failure. Many pipelines are successfully inspected by magnetic flux leakage (MFL) pigs to detect corrosion. However, there is a subset of pipelines for which MFL is not feasible. To inspect those "unpiggable" pipes will require a more adaptable technology. Remote field eddy current (RFEC) is an alternative inspection technology and potentially capable of detecting corrosion defects in pipelines not "piggable" by conventional technologies. Traditional RFEC is configured with a large excitation coil, only slightly smaller then the inside diameter of the pipe, and with multiple small sensors. This traditional exciter coil configuration often cannot pass by internal pipeline restrictions.
