Advanced Ultrasonic Testing
| Resources |
Automated Ultrasonic Testing (AUT) uses a multi-channel digital ultrasonic system with robotic scanner to perform on-stream inspection on varying equipment items.
The technology uses Pulse-Echo (C-Scan) techniques for corrosion mapping, hydrogen induced cracking and other related cracking; Time of Flight (TOFD for heavy wall reactors, vessels and piping, Phased Array technique for examination of complex geometries such as nozzles, branch connections, flange faces and much more.
Its primary application is to collect and image data in real-time prior to equipment shut-downs or turn around so as to assess damage and prioritize maintenance activities. The technique, due to its repeatability and imaging is excellent when monitoring critical flaw growth or when determining defect morphology.
Productivity
A two man crew using the automated ultrasonic testing (AUT) technique is capable of achieving:
- Nearly 500 square feet of surface area when performing corrosion mapping.
- 75 liner feet of weld inspection when performing pulse-echo flaw detection and sizing.
- 300 linear feet of equipment weld when using the time of flight or phased array flaw detection and sizing.
Reporting
Data interpretation and reporting is nearly instantaneously allowing C-SCAN, B-SCAN, A-SCAN images to be generated on-site.
