Ultrasonic Testing in lieu of Radiographic Testing Martin van den Heuvel MISI-Consultancy KINT Symposium October2019 Agenda UltrasonicTesting in lieu of Radiographic Testing: ‘UT ilo RT’ ▪ NIL ThinPlate ▪ Innovationin NDT The case for change ▪ WhyuseUT iloRT ▪ SuitableUT Techniques Business Cases ▪ Project ▪ Maintenance Way forward ▪ Collaboration UT in lieu of RT: historic information NIL Thin Plate project 1992 Objectives ▪ To assess the reliability of mechanized ultrasonic inspection. in comparison with the 'standard' non-destructive inspection techniques (i.e. standard radiography and manual UT) for detection of defects in welds in steel plate in the wall thickness range 6-15 mm. ▪ To contribute to the development of suitable acceptance/rejectance criteria and, if necessary, initiate their implementation criteria in national and international regulations on non-destructive testing Conclusion ▪ The detection reliability of mechanized ultrasonic testing techniques is at least as good as but usually better than that of conventional non-destructive testing techniques such as manual ultrasonic testing and standard radiography. Improvements since 1992 ▪ Mechanized (PA)UT is standardized and thus reliable Automated UT (AUT) and semi-automated UT with encoded scan enables permanent record keeping of UT inspection data ▪ Data storage is now common practice Innovation in NDT (These Wassink 2012) Key points ▪ It takes a long time to develop and implement changes in NDT applications ▪ Collaboration of all parties is key, the Cyclic Innovation Model is a way to shorten the time ▪ Entrepreneurs are needed to make it a success
