Infrared/ Thermography Testing (IT)


Infrared testing (Thermography) is a NDT used to detect small temperature difference to detect deterioration in assets and plants.

Thermography supports the maintenance of plants and equipments with its fast and cost effective application. In this application doesn’t require contact with the test piece in not required it is used in power plants, oil and gas, petrochemical, boilers etc.

Early detection of any problems helps in preventing any unscheduled outages, improves reliability, productivity and safety of the assets and equipments and any corrective measures can be implemented depending on the data available.

objects release infrared radiation (Thermal waves) which is invisible to naked eyes. An infrared camera measures thermal energy and map temperature difference of the object. This image captures the heat flow to, through and from the object. The analysis of this image can highlight problems such as corrosion, erosion as well as flaws in the materials such as air gaps or inclusions.

As nearly everything becomes hot before failing, thermography is an important diagnostic tool to find deterioration of the equipment. Many times object that show low thermal energy indicates loss of power and energy faults.

Benefits of infrared testing (thermography) include:

  • Discovering defects in pipes, metals and temperature variances
  • Observing areas that are inaccessible for other NDT methods.
  • Early stage defect detection and material wear.
  • Detection of corrosion and erosion.
  • Inspection of large areas.
  • Real time defect detection
  • It doesn’t affect production process

ANDT’s inspectors possess expertise in using this technique and interpreting the thermal images, this helps us to provide necessary data to optimize service life of the equipment that assists in achieving maximum productivity.

Our inspectors are qualified in ASNT level II and III and we used advanced thermography to detect problem areas.

By choosing ANDT as your partner for Inspection you have Quality Assurance that your production and maintenance schedules are being met.
