    Triton LFET System

    (Low Frequency Electromagnetic Technique)

  • Utilizes up to eight channels with low signal-to-noise ratio
  • Detect flaws, including corrosion cells, hydrogen damage, caustic and phosphate gouging, oxygen pitting, ID pitting, corrosion, erosion and magnetite blockages
  • Scans ferrous and non-ferrous materials
  • Display high resolution, real time, 3-D color graphics of the scan results
  • Results can be saved for further analysis or permanent archiving

    Triton LFET Scanners

  • Flat scanners can be used on plates
  • Contoured to scan tubes and pipes of any diameter
  • Sensors are only a few millimeters in diameter giving greater detection capabilities for smaller flaws such as pitting
  • For bends, we have customized curved scanners for scanning the extrados and sides of bends

    Advantages over Competing Technologies

    Triton LFET System

  • Unlike competing products, our Triton LFET system requires minimal surface preparation to be effective
  • Efficiency is due to the fact that the our LFET scanner is a dry-contact method; the scanner surface containing the sensors does not need to touch the surface being tested
  • Operates at low frequencies (usually 10Hz or lower), therefore; the electromagnetic field is not affected by any non-magnetic deposits, including iron oxide/scale
  • 2,000 – 3,000 linear feet of surface material can be scanned in a 10-12 hour shift with one inspection team
  • Scanning can be conducted from skyclimbers or hard scaffolding

    Limitations of Competing Technologies

    Ultrasound (UT)

  • For ultrasound, surfaces need to be sandblasted, or spot-prepared for individual discreet UT thickness readings
  • Does not provide rapid scanning coverage; UT merely involves spot checks
  • Electromagnetic Acoustic Transducer (EMAT)

  • For the EMAT method, surfaces need to be sandblasted
  • The EMAT method does not provide rapid scanning coverage, EMAT only scans a strip less than one-quarter-inch (¼″) wide
  • X-Ray (RT) / Radiography

  • X-Ray methods have inherent limitations because access is required on two sides of the sample. There are also restrictions to the surrounding area of the sample being tested
