I have bought a couple of 12" WN flanges class 300 #RF and i have to drill them urgently. Suppliers in this period are closed for holyday, so I have to do it by myself. Can you tell me the distance between the bore axis (1/2") and the RF plan? Somewhere you read 0,94", elsewhere 1".
How should be the plate thickness for a 12" flanges? 1/4" or 1/8"? Thanks in advance for your reply.
