Dear Experts,
Case 1) As per API 650 2013ed. para. 8.1.2.9 "When bottom annular plates are required by 5.5.1, or by M.4.1, the radial joints shall be radiographed". If annular plates were required as per Seismic calculation instead of 5.5.1 or M.4.1, Radiographic examination is still Mandatory?
Case 2) As per para. 7.3.2.1 and Annex T (NDE requirements summary), Shell plate butt welds if approved by Purchaser could be subjected to Ultrasonic testing in lieu of Radiographic examination as per requirements of Annex U. Do this requirement (UT instead of RT) applicable to Annular plate Radial joints?
Regards,
