What Is RFT
RFT employs alternating current to induce an electromagnetic field in ferritic materials (such as steel pipes).
Electric coils detect flaws and measure material thickness in the inspected part.
Equipment We Use
RFT Probe Configuration:
- RFT probes consist of one or several transmitter coils positioned two tube diameters apart from the receiver coil.
- The magnetic field created by the transmitter coil travels through and out of the tube wall, both radially and axially, towards the receiver.
- Through-transmission allows equal sensitivity to detect external and internal defects.
RFT Application
Coupling Paths:
Direct Path:
- Inside the tube, rapidly attenuated by circumferential eddy currents induced in the tube’s wall.
Indirect Path:
- Originates in the transmitter’s magnetic field diffuses radially outward through the wall.
- At the outer wall, the field spreads rapidly along the tube with little attenuation and re-diffuses back through the pipe wall, becoming the dominant field inside the tube at the receiver.
- Anomalies in the indirect path cause changes in the magnitude and phase of the received signal, allowing for defect detection.
Advantages of Choosing RFT
Suitable for ferromagnetic materials (like steel).
Highly sensitive to wall thickness variations.
Equal sensitivity at the inner and outer surfaces.
Can be used with lesser fill factors than other electromagnetic testing techniques.
