At TesTex, we know your turnaround depends on our turnaround.

Products

TesTex uses a variety of state-of-the-art electromagnetic techniques to scan for defects in both ferrous and nonferrous materials and structures.

LFET Products

Low Frequency Electromagnetic Technique (LFET) products are used to inspect storage tanks, other convex or concave ferrous surfaces, as well as nonferrous metal tubing/piping surfaces.

RFET Products

Remote Field Electromagnetic Technique (RFET) products are used to quickly and accurately inspect ferrous tubing found in heat exchangers and drum-to-drum boiler generating banks.

BFET Products

Balance Field Electromagnetic Technique (BFET) products are used to detect surface and sub-surface cracking in welds and base metals.

ECT Products

Eddy Current Technique (ECT) is used to quickly and accurately inspect non-ferrous metal tubing from the tube internal dimension (ID).

Ultrasound

TesTex has enhanced ultrasonic (UT) inspection for many different applications, including tank shells, UT prove-ups, finned tubes and waterwalls.

Probes

TesTex produces standard and custom probes (and calibration tubes) for all of its ID (internal dimension) inspection equipment.

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

Probes

RFET Straight Probes
RFET Flex Probes

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

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
