Dear All,

Who can help me about a case regarding a pressure vessel stamped as "U2" which was manufactured, approved and shipped to the company i work for. But during the receiving inspection, in order to fit it to its final position, and according to internal inspection, some defects have been revealed on the visual weld inspection on the root of one of its nozzle like undercuttings, lack of fusion and concavity. We asked for the x-ray film to the manufacturer and they have sent to us but the result was approved. Then we have decided to perform another x-ray  on that joint to confirm the manufacturer x-ray, using the same x-ray techinique and the result revealed porosities out of ASME VIII div 2 requirements. So, in this case, if we decide to repair this joint, would we need to classify the vessel again ?

Best regards,


Guttemberg Souza
