Ability to accurately size and monitor pre-existing or growing in-service discontinuities becomes more and more important in chemical and refining plants especially when a risk based inspection (RBI) approach is used. With the industry s growing need for more reliable, simpler, accurate and cost effective techniques, time of FliGhT DiFFRaCTiON (TOFD), which was originally developed for crack-sizing in nuclear applications, established itself as a widely used tool for flaws detection in welds. This unique ultrasonic technique has big advantages in speed, detection of defects and is the most accurate defect sizing technique in general use. One of the important advantages of using TOFD for weld inspection is the absence of radiation. Furthermore, in several validation projects TOFD has proved itself to be a technique, which combines a high detection rate with a very high reliability in pre-service and in-service WelDiNG iNSpeCTiONS WiTh hiGh DeTeCTiON RaTe time OF Fli GhT DiFFRaCTiON (TOFD)SGS iNDuSTRial SeRviCeSCOMpeTeNCe CeNTReNDT Special ExaminationsMalledijk 18, Postbus 2003200 AE Spijkenisse, NLT +31 181 693 703F +31 181 693 587 09/2008 SGS.
