NOTES
1. Raised face height (f=2.0mm) not included in thickness (C) and length through hub (Y1, Y2)
2. For Slip-on, Threaded, Socket-Welding, lab Joint flanges, the hub shall be tapered 7° max. or vertical from base to top.
3. Blind Flanges may be made with the same hub as that used for Slip-On flanges or without hub.
