Re: [MW:26436] Radiography requirement of Annular Plate butt welded joint of the Tank / API 653/650

Hi

I believe you are repairing the tank.

If so, as per clause 12.2.1.4 of API 653, each annular plate joints shall be radiographed where the shell course rests on the annular plate.

Dear Prasad

Thanks for the response. However, I understand that Section 8.1.2.9 does not refer to RT requirements for Group 1 materials. In that case RT won't be required for butt welded Annular Plate I believe. 

Thanks and Regards
