Straddle bolt holes
Straddle bolt holes
(OP)
When flanges are being installed, the bolt holes need to straddle the center lines. Why?

RE: Straddle bolt holes
-If they're on cL, the Section Modulus of the Bolt group is better for loading on cL [i.e., lower "extreme" fiber stress for horizontal/vertical moments]
-Easier to scribe a centerline if there's no hole in the way
-It will fit to everybody else's piping, since they straddle cL's. Most Standard Fittings, Valves, etc., have bolt quantities in multiples of 4, & straddle cL's.
There's probably a bunch more too - guys??
