SPECIALISED TESTING SERVICES
Ultrasonic Phased Array (PA) testing
Ultrasonic Phased Array utilizes multiple ultrasonic elements to create sound paths.
Advantages:
- Accurate defect sizing & greater detection
- Rapid scanning
- Optimised beam angles perpendicular to defects
- Scans can be electronically saved for permanent records
Applications:
- Flange face testing
- Weld testing
- Stress corrosion crack testing
- Shaft testing
- In-service Pressure vessel and pipe testing
- Testing of complex geometrical parts
- Corrosion mapping and trending


Ultrasonic Time Of Flight Diffraction (TOFD) testing
TOFD utilizes a transmitting & receiving probe located equidistant over the weld centre.
Advantages:
- Accuracy and repeatability
- Rapid scanning
- Scans can be electronically saved for permanent records
- Real time results
- Manual & automated testing
- Defect detection of is not dependent on orientation or type of flaw.
Applications:
- Weld testing
- Hydrogen induced cracking
- In-service Pressure vessel and pipe weld testing
- Testing of welds after Post Weld Heat-Treatment (PWHT)
- Pressure Equipment- Service Life Assessment (Monitoring of welds)
