Ultrasonic Thickness Gauging

UTG is a method of performing non-destructive gauging (measurement) of the local thickness of a solid element (typically made of metal) based on the time taken by the ultrasound wave to return to the surface. This type of measurement is typically performed with an ultrasonic thickness gauges. We offer on-site thickness gauging services for assessing corrosion in process plant, piping & equipment. We are equipped with state of art ultrasonic thickness gauges having the latest through coat technology where removal of paint from the surface is not required.


Advantages:

  • Requires access from only one surface
  • Rate of corrosion & erosion is measured

High temperature thickness gauging (up to 350 degree C)

Thickness measurement at elevated temperature is a special category. Standard transducers are not designed to withstand elevated temperatures and will get damaged / destroyed due to varying thermal expansion coefficients of the materials used to construct them. Variation in material temperature affects sound velocity and accuracy of thickness measurements. We use special transducers & couplant with A-Scan gauges to perform this task.

Oxide Scale Thickness Measurement

We offer on-site oxide scale thickness measurement services to measure the thickness of oxide scale build-ups inside boiler tubes. The gauge simultaneously displays the metal thickness of the boiler tube and the thickness of the oxide layer. Knowing the thickness of the oxide scale helps predict tube life.
