Description
Double Studded Adapter (DSA) is a flange with a through bore and a ring groove on each side, bolt hole sets on each face, and installed with tapped end studs and nuts. It is different from a spacer flange; the two sides are different in size and/or pressure rating. Double studded adapter flanges are commonly used to connect different nominal sizes, pressure ratings, and configurations.
