Remote Field Testing

Remote Field Testing (RFT) is an Electromagnetic method of Non-Destructive Testing whose main application is finding defects in steel pipes and tubes. RFT may also be referred to as RFEC (remote field eddy current) or RFET (Remote Field Electromagnetic Technique). An RFT probe is moved down the inside of a pipe and is able to detect inside and outside defects with approximately equal sensitivity (although it can not discriminate between the two). Although RFT works in non-ferromagnetic materials such as copper and brass, its sister technology Eddy Current Testing is preferred.
