Methodes used are ABI scan and TOFD. I was reject all scan result of joints scaned only one side. : My questions are. : 1. Are ABI scan and TOFD can inspect for joints pipe to fitting (L bowls and flanges) in diameter range of 3-6"? How to full coverage scan. : 2. Which is the best equipment to inspect the above mentioned material? : Thank you, : Dao Huu Xuan, Vietnam ------------ End Original Message ------------ Dear Sir, It is nice to see someone having similar interests. I think method (technic) described below is more efficient and better than modern advanced and complicated technics for UT of pipe thin welds (2-8 mm) and thin welds. We have long term experience in domain of UT of pipe welds. Our technical solutions of pipe welds UT are commonly performed in power engineering, thermic and fuel installations etc. Actually, after some modifications we are offering equipment and technic for UT. This technic is available in the Internet ( http://www.ultrasonic.home.pl/pdf/niezawodnosc/ibus_td_en.pdf ). Most important technic features are: - its very high sensitivity: 1mm hole is easily detected with difference between reading and noises over 20dB (page 15, Fig. 1-5) - fast testing and immedietaly valuation - technic validation with usage of DAC technic according to requirements of EN – ISO/IEC 17025 Testing can be performed manually or it can be joined with encoder for registration testing results. If you need some more informations, please write to me.
