    ASME PCC-2 Fillet Welded Patch Repair

    CMaldini, I'm not really sure of the validity of your approach, as once patched it becomes difficult to monitor the thickness of the LTA region you will have over plated. In my experience for higher pressures, the PCC-2 patch plate requirements can be impractical due to the eccentricity check...

    ASME PCC-2 Fillet Welded Patch Repair

    Hi CMaldini, In my experience, I have always designed patch plates considering the design pressure. Even if an LTA remains, and the patch plate is not covering a hole, I always take this approach in case the thinning mechanism was to continue. This could certainly be the case for loss...

    ASME PCC-2 Fillet Welded Patch Repair

    r6155, With all due respect, I haven't asked anyone to check my work, and I wouldn't expect any forum members to provide free consultancy. This is a debate on what the code is doing, and at no point have I asked anyone to check my actual calculations relating to the project I am working on...

    ASME PCC-2 Fillet Welded Patch Repair

    Hi r6155, Yes these aspects have been considered as part of the repair specification, but they don't relate to my query in the OP. Thanks, JAR10

    ASME PCC-2 Fillet Welded Patch Repair

    Hi r6155, Thanks for the reply. I understand the thickness requirements for the patch plate will be greater than those for the shell due to the eccentricity loading check. Looking further into Equation (5) I have summarised my thoughts below: I think the equation does make an assumption...

    ASME PCC-2 Fillet Welded Patch Repair

    Hi everyone, I am looking at specifying a fillet welded patch plate repair to ASME PCC-2. I have demonstrated the proposed patch plate thickness to meet the requirements of the original vessel design code, and I have sized the attachment welds to Equation (4) within Article 212 of PCC-2. These...
