Remote Field Testing (RFT) for Tubes
Remote field testing (RFT) is used for tubing that is ferromagnetic, such as carbon steel or ferritic stainless. It is used for detecting and measuring volumetric wall loss from erosion and corrosion. Remote field is a good alternative to IRIS to use on generating banks when time or budget constrictions are impacting the outage/shutdown. Remote field testing eliminates the headaches of plugging tubes/ locking out mud drum to fill generating bank tubes with water, and can be performed in a shorter amount of time than IRIS.
