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 LFET System

  • Utilizes up to eight channels with low signal-to-noise ratio
  • 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
  • Display high resolution, real time, 3-D color graphics of the scan results
  • Results can be saved for further analysis or permanent archiving

Scanners

Tube Scanner
Flat Scanner
Pipe Scanner
High Temperature Scanner
Adjustable Scanner
Low Profile Scanner

Triton LFET scanners

  • Contoured to scan tubes and pipes of any diameter, as well as plates
  • 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 no-contact method; the scanner surface containing the sensors does not 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

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 does 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
