Guided Wave Testing

guided wave testing
Since 1967, ATS has been a leading NDT company offering a wide variety of services to many industries.

Applied Technical Services, Inc. (ATS) provides guided wave testing as a productive and efficient method for effective pipeline surveying by applying low-frequency ultrasonic waves originating from a single test location. Cracks and corrosion loss in above ground storage tanks, insulated and buried pipes can be identified in addition to their estimated location and size.

As a time-saving measure in reducing cost, guided wave testing allows inspection and evaluation of large sections of pipeline which may include insulated pipes that can remain unaltered while staying in service without the need to remove contents from the lines as a beneficial result. In addition, stress cracks can be identified in above ground storage tank steel plates for multipliable use.

Structural Health Monitoring (SHM):

ATS can implement structural health monitoring (SMH) for fixed installation for continual and long-interval data-collection and detection monitoring in wide-ranging areas.

Guided wave technology detects flaws in:

  • Anchor rods
  • Heat exchanger tubing
  • Metal structures
  • Pipelines
  • Steel cabling


  • Ability to inspect underground piping, pipelines and insulated pipes.
  • Pipe size outside diameter for inspection range from 0.25-inch to 60-inch.
  • Operating frequency range between 8 kHz to 250 kHz; at higher frequencies it can lower the near-field zone as well as the dead zone at less than 0.5 ft.
  • Test above ground tanks and pressure vessels for stress cracking.


  • Oil & Gas
  • Petrochemical
  • Power Generation
  • Industrial plants and more
