ToFD screening has been developed jointly between Sonomatic and Shell Global Solutions with the objective of providing a method of rapid, yet accurate corrosion mapping. The ToFD footprint at the internal surface is approx 2x the material thickness. Linear scanning speeds are very high, and a special range of scanners have been developed by Sonomatic’ mechanical design engineers, and software by our software engineers to facilitate rapid scanning. The lateral resolution is poor, but the thru-wall resolution is remarkably high.
The nature of the reflection of the ultrasound from eroded/corroded areas in the TFD pitch-catch arrangement makes it ideal for the detection of Weld Root Erosion/Corrosion. This approach has a proven track record as an accurate method for the detection and monitoring of corrosion and erosion damage in the weld and heat affected zones. |
