Corrosion Fatigue Cracking Inspections at OVEC
The Balanced Field Electromagnetic Technique (BFET) can detect corrosion fatigue cracking by sending an electromagnetic signal into the metal. A detector coil measures any change in the signal and can size cracking within 10% accuracy through the use of calibration standards. TesTex has developed and customized a rotating BFET probe for sizing corrosion fatigue cracking. This probe is able to travel through bends for boiler tubes with a inside tube diameter of 2″ or greater.
