API Flange

Description

Double Studded Adapter Flange (DSAF) or Double Studded Adapter (DSA) 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 Blind Flange with different nominal sizes, pressure ratings, and configurations.

Double studded adapter flange is a combination of flanges of different sizes and pressure ratings.

Sanmon supplies ideal DSA for reliable and consistent performance on their production system. Our adapter flanges are in various sizes and pressure ratings as per customer’s specified thickness, consistent with design considerations. It is the important device to connection the different flange for wellhead, so the material of the body and studs and nuts shall be conforms the related requirements. The size is in accordance with API 16A flange certification.
