API Spec 6A Double Studded Adapter 13-5/8" 10,000 Psi X 13-5/8" 2,000 Psi.
Double Studded Adapter is a flange with a through bore and a ring groove on each side, drilled and tapped bolt hole sets on both sides and tapped end studs complete with nuts fitted on both sides. Unlike a spacer, the two sides are usually different in size and/or pressure rating. Double-studded adapter flanges are commonly utilised to connect and adapt flanges with different nominal sizes, pressure ratings, and configurations.
