Triton RFET System

(Remote Field Electromagnetic Technique)

Triton System

Triton RFET System

  • Utilizes up to eight channels with low signal-to-noise ratio
  • Detects and quantifies flaws, including corrosion, erosion, pitting, cracking, metallurgical defects
  • ID inspection of straight tubes, U-bends, or small diameter pipes
  • Works with ferrous and non-ferrous metals
  • ID or OD scale does not affect signal
  • Displays high resolution, real time, 3-D color graphics of the scan results
  • Results can be saved for further analysis or permanent archiving

Triton RFET probes

  • Provides full circumferential coverage over entire length of tube or pipe
  • Probe sizes from 0.21″ (8mm) to 6″ (150mm)
  • Probe fill factor can be as low as 40%
  • Single channel probes operate in absolute or differential modes
  • Multi-channel probes allow for higher flaw resolution
  • Flex probes inspect tube and pipes with bends

Triton RFET System Advantages Over Competing Technologies

Triton RFET System

  • Unlike competing products, our Triton RFET system requires minimal surface preparation to be effective
  • Efficiency is due to the fact that the our RFET probe does not require a high fill factor and is not affected by scale
  • Operates with a wide frequency range (5Hz – 7.5kHz) allowing the system to inspect ferrous and non-ferrous materials
  • 300 – 400 tube can be inspected in a 10 – 12 hours shift
  • Probe lengths up to 150 feet without signal pre-amplification
  • Probes do not use permanent or electo magnets

Other methods of inspection include

Internal Rotating Inspection System – Ultrasound (IRIS UT)

  • For IRIS UT, surfaces need to be thoroughly cleaned
  • Does not easily penetrate through oxides, scale, deposits and debris
  • Slow inspection technique, 100 tubes per shift

Magnetic Flux Leakage (MFL)

  • For MFL method, surfaces need to be thoroughly cleaned
  • MFL probes need very high fill factor
  • Cannot determine flaw sizes
