The Triton Scanning System LFET option:

  • Utilizes from two – eight channels with low signal-to-noise ratio
  • Can detect flaws, including corrosion cells, hydrogen damage, caustic and phosphate gouging, oxygen pitting, departure from nucleate boiling, ID pitting, corrosion, erosion and can also determine magnetite blockages
  • The system can display high resolution, real time, 3-D color graphics of the scan results. Results can be saved for further analysis or permanent archiving

See below for information about the Triton LFET Scanners

TesTex Triton LFET scanners

  • Can be contoured to scan tubes and pipes of any diameter, as well as plates
  • Scanner sensors are only a few millimeters in diameter giving greater detection capabilities for smaller flaws such as pitting
  • For bends, TesTex created special curved scanners for scanning the extrados of bends and sides as well

Triton System: Advantages Over Competing Technologies

TesTex’s Triton Scanning System using LFET option

  • Unlike competing products, the TesTex Triton LFET option requires minimal surface preparation to be effective
  • The Triton’s efficiency is due to the fact that the TesTex LFET scanner is a no-contact method; the scanner surface containing the sensors does not touch the surface being tested
  • The Triton LFET option operates at low frequencies (usually 10Hz or lower), therefore; the electromagnetic field is not affected by any non-magnetic deposits, including iron oxide
  • 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

Other methods of inspection include:

Ultrasound (UT)

  • For ultrasound, surfaces need to be sandblasted, or spot-prepared for individual discreet UT thickness readings.
  • The ultrasound method doe not provide rapid scanning coverage; UT merely involves spot checks

ElectoMagnetic Acoustic Transducer (EMAT)

  • For ElectroMagnetic Acoustic Transducer method, surfaces need to be sandblasted
  • The EMAT method does not provide rapid scanning coverage, EMAT only scans a strip less that one-quarter-inch (¼″) wide

X-Ray (RT)

  • X-Ray methods have obvious deficiencies, including getting coverage and limitations due to testing while other outage activities are occurring
