    Maximum patch size for tank shell replacement

    Thanks JStephen. If to replace part of the ring, do I need to consider that when cut out the old shell, the roof will collapse?

    Maximum patch size for tank shell replacement

    Is there a maximum patch size for tank shell replacement? If yes, how to determine the maximum size? I don't see it is required in API 653, but our client asked about the maximum size of the patches. Thanks,
