What is a Double Studded Adapter Flange (DSA)?

A Double Studded Adapter Flange, or DSA flange, is a key connector used in surface wellhead systems. It features two studded flange faces—one on the top and one on the bottom—allowing operators to join components with different sizes, pressure ratings, or flange types. These flanges are essential for flexible and secure integration of BOPs, valves, spools, and other API 6A wellhead components.
