American Welding Society Forum
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.
ASME B&PV Code sections only address new construction.
NBIC addresses in-service inspection and repair of vessels. ASME does have a standard for assessing the condition of a vessel that isn't part of the B&PV code. The title escapes me for the moment and I don;t recollect it addresses the repair of corroded or damaged flanges. Sorry I can;t be more helpful.
Thanks for the reply. I will do a little more digging. Have a good one.
