Hello All,
First time posting in this forum. I have a pressure vessel that has RTJWNF and the bolt hole area and the "retention ring" is in pretty bad shape. My question is, is there somewhere that gives a tolerance for corrosion and wall loss on just the bolt hole area? The faces of the flanges are fine it's just the bolt hole and retention ring areas. I would personally like to replace them but I would like to have something in the code to reference the Maintenance Manager to. Thanks for any insight.
