Double Studded Adapter Flange

Product Description

Double Studded Adapter Flange is an adaptor flange, component with studded connections on each end, used to connect flanges with different nominal sizes, pressure ratings and configurations.It is used for switching high pressure wellhead and Christmas tree system to normal pressure piping system.

Double Studded Adapter Flange is the part which is often used in the wellhead system, DSA Flange is designed and manufactured in accordance with API 6A standard, DSA Flange usually has double studded flange connections.

DSA Flanges are much shorter than a spool, therefore useful where space is at a premium. Available in sizes from 2-1/16" to 21-1/4" and pressure ratings of 2,000 psi to 20,000 psi.

Enerpal offers all sizes and pressure ratings DSA Flange used for oilfield applications. Also available in API to ANSI configurations as well depending on the customer's requirements.

Key Applications in Oil and Gas

  • Wellhead Assemblies: DSA Flanges are commonly used in wellhead assemblies, where they connect different components of the wellhead system. This ensures a secure and leak-proof connection, which is crucial for maintaining the integrity of the well and preventing blowouts.
  • Pressure Control Equipment: In pressure control applications, DSA Flanges are used to connect various pieces of equipment, such as blowout preventers (BOPs) and choke manifolds. Their ability to handle high-pressure environments makes them indispensable in maintaining control over well pressure during drilling and production operations.
  • Pipeline Connections: DSA Flanges are also employed in pipeline systems to connect sections of pipe with different flange sizes. This is particularly useful in situations where pipeline modifications or repairs are necessary, allowing for seamless integration of new components without the need for extensive rework.
