Swivel Flange

what is a swivel flange ?

A swivel ring flange is a two-piece flange that is often used for offshore pipelines and other applications in the offshore industry. A swivel ring flange has a heavy forged welding hub that is attached to a forged ring that can be turned to serve as a mating flange to a weld neck or another flange.

Materials

Standard materials are A105 with a minimum yield of 42,000 psi, and the welding end has more thickness to make up for higher yield pipe. These flanges can be made of high-yield materials like ASTM A694 or ASTM 707, and they can also be made to the customer's specifications.
