Remote Field Eddy Current Testing

Remote Field Eddy Current Testing Remote Field Testing (RFT) is one of the several electromagnetic testing methods commonly employed in the field of non-destructive testing. RFT may also referred to as RFEC (Remote Field Eddy Current) or RFET (Remote Field Electromagnetic Technique). RFT is primarily used to inspect ferromagnetic tubing since conventional ECT have difficulty in inspecting the full thickness of the tube wall due to the strong skin effect in ferromagnetic materials.

Advantages of RFT:

  • Detection of wall loss
  • Ideal for ferrous tubes
  • RFT can detect defects away from tube support plate and tube sheet
  • Detect localized corrosion/erosion
  • Inspect ferromagnetic materials (carbon steel and stainless steel)
