Ultrasonic Thickness Gauging



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. These gauges have in-built data logger for storing thickness readings, A-Scans, B-Scans which can be later transferred to computer for generating reports.




Advantages:

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


Limitations:

  • Need Surface preparation
  • Need Couplant

High temperature thickness gauging (up to 350 degree C):


High temperature thickness gauging 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 ofoxide scale build-ups inside boiler tubes.The gauge simultaneously displays the metalthickness of the boiler tube and the thicknessof the oxide layer. Knowing the thickness of theoxide scale helps predict tube life.
