Nondestructive Testing

We are pleased to offer a broad selection of the most state-of-the-art inspection methods in the business. Our nondestructive examination techniques include:

Acoustic emission testing

Corroscan/C-scan coating assessment services

Dye and liquid penetrant examination

Electromagnetic testing

  • Alternating current field measurement (ACFM) and alternating current potential drop measurement (ACPD) for crack detection and sizing through coatings and scale
  • Eddy current testing (ECT) or Eddy current array (ECA) for crack detection and sizing
  • Magnetic flux leakage (MFL) or magnetic flux exclusion (MFE) testing for pipelines, tank floors, and wire rope
  • Saturated low frequency eddy current (SLOFEC) for testing of storage tanks, pipelines, pressure vessels, caissons and risers
  • Magnetic-particle inspection (MT or MPI), both wet and dry

Exchanger tube inspection

  • Remote field testing (RFT)
  • Eddy current tube inspection (ECT)
  • Internal rotary inspection system (IRIS) ultrasonic tube testing
  • Near-field testing (NFT)
  • Eddy Current Array (ECA)
  • Magnetic flux leakage (MFL)
  • TubePro 2-D/3-D Reporting Software

Guided wave testing (GWT) using the GUL G3 Wavemaker

Infrared thermography

Leak testing

Positive material identification (PMI) / Arc analysis using the Arc-Met 8000

Radiographic testing (RT)

  • Digital radiography (real-time) in fully-equipped mobile X-ray units
  • Film radiography
  • Open vision – real-time radiography for corrosion under insulation (CUI)
  • Radiographic examination, including iridium 192, gamma ray, cathode ray tube (CRT), cobalt 60 and LixiÒ

Specialized techniques for specific damage mechanisms

  • Electromagnetic acoustic transducer (EMAT) (non-contact)
  • Elevated temperature flaw detection (700°F)
  • Long-range ultrasonic testing (LRUT)
  • Phased array ultrasonics
  • Time of flight diffraction ultrasonics (TOFD)

Visual inspection (VT)
