Re: [MW:4817] UT for IBR

dear all!

 

ibr allows you if you requested, thru letter, prior to do so..

 

please check with IBR 1950 regulation 265[b] and 360[f] for resolve your problem.

Hi Ramesh, Referring the UT of IBR drum, some brief considerations I hope will be helpful for you : 1. UT and RT are complementary and the best result is when you  use the both; 2. For 100 mm thickness, UT achieves a better sensitivity than RT, especially for higher angled planar discontinuities, but lower (acceptable) accuracy in discontinuity sizing and diagnosis; Some minimum conditions are necessary for a well done UT: 1. Base material and filler material: close-grained unalloyed steel (or alloyed, but non-austenitic); 2.UT procedure containing (preferably) well known reference documents (ASME, EN, etc.) for UT technique and specific acceptance criteria agreed by client and/or national regulations (if pressure vessel, for example); 3. NDT (UT) certified and authorized personnel, at least level 2, according to (preferably)  recognized standards (SNT-TC-1A, EN 473, etc.); 4. Calibrated ultrasonic instruments, transducers, reference blocks, etc.; 5. Part configuration enables the required  directions of ultrasonic testing and assures the width of scanning area; 6. Scanning surface conditioning is necessary. Note: If IBR material is austenitic steel or other coarse-grained steel, UT can be possible but RT is better.     --- On Sat, 4/10/10, Ramesh Barot <rameshnbarot@yahoo.com> wrote: From: Ramesh Barot <rameshnbarot@yahoo.com> Subject: [MW:4779] UT for IBR To: "Materials Welding" <materials-welding@googlegroups.com> Date: Saturday, April 10, 2010, 11:18 AM Dear All,   IBR allows for ut? MY case is 100mm thk steam drum. I want to do RT of upto 15mm for saving time and after that I want to clear it by UT, is it possible?   IBR allows for this?   Thanks, With Best Regards, Ramesh Barot -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding-unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
