7 1/16 5000# API flange

[Marlin700]

Currently sourcing stud-bolts and Gaskets for a 7.1/16" 5000# API weld neck flange. ASTM A182 F53/55 Duplex. Two similar flanges are to be mated back to back.

Could someone please advise stud bolt length and diameter and also gasket type and size for subsea use?

I think they are 1.5" diameter?
Gasket R46?

Many Thanks

According to my Flange Slide Rule (free from Woodco USA), 7-1/16 5M API flange is either a R46 or RX-46 ring gasket and the 12 stud bolts are 11-1/4" long and 1-3/8" diameter.

Or check API 6A...
