J.B. 11:44 Apr-23-2019 Re: SDH EQUIVALENCE In Reply to Vincent CHARDOME at 10:54 Apr-23-2019 . Reading your request I First thought: Typical question to be answered in the famous Josef Krautkramer - Book "Ultrasonic Testing of Materials" He had put some nice graphics and thumb rules in his book, which I always used in my UT-Lessons. Next - reading the link to this older post of Ed. Ginzel referencing Ermolov made me think: You should use CIVA simulation software to get the full insight into this topic. But you may simply follow the link to the page of the CIVA makers EXTENDE: Here you find lot of stuff: http://www.extende.com/ultrasound-calibration-defects http://www.extende.com/ut-sdh-side-drilled-holes-at-different-depths-and-contact-probes http://www.extende.com/ut-sdh-side-drilled-holes-at-different-depths-and-immersion-probes http://www.extende.com/comparison-fbh-sdh It is not easy to access those pages just directly from the EXTENDE Homepage (http://www.extende.com/) but if you look for the sitemap (http://www.extende.com/site-map) you may have a view about all the helpful information they offer under the headline "Experimental validation of models in UT"    Reply  Translate  Close

The ergonomic design, long battery life, and intuitive touchscreen mean you can inspect more areas faster than ever without fatigue. > 5 Showcases5 Videos Ultrasonic Testing Immersion Tanks with Unmatched Scanning Features StandTecScan Systems TecScan’s non-destructive testing Ultrasonic Immersion Tanks & scanners are designed for high pe ... rformance and demanding NDT testing applications. Our Scan3D™ line of High Precision Immersion Tanks are specifically designed for automated ultrasonic testing of complex composites parts used in aerospace and industrial applications. > 5 Showcases4 Videos UCI Hardness Tester NOVOTEST T-U2 StandNOVOTEST Ltd UCI hardness tester NOVOTEST T-U2 is is used for non-destructive hardness testing of: metals and ... alloys by scales of hardness: Rockwell (HRC), Brinell (HB), Vickers (HV); non-ferrous metals, alloys of iron etc., and using five additional scales for calibration; with tensile strength (Rm) scale determines the tensile strength of carbon steel pearlitic products by automatic recalculation from Brinell (HB) hardness scale. > 5 Showcases5 Videos Lyft™: Pulsed Eddy Current Reinvented StandEddyfi PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u ... nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft? > 4 Showcases5 Videos more Showcases
