The Swivel-Ring Flanges permit 360° rotation of an outer ring around the hub, to allow easy alignment of bolt holes when attaching to a mating standard flange for subsea applications. This capability to have the ring to swivel or rotate is important when only a single diver is available to align and make up the flange connection.
Swivel-Ring Flanges can be designed for any size and pressure rating to meet applicable dimensions and gasket types of any recognized flange specification, such as ASME B16.5 or MSS SP-44.
Non standard Swivel-Ring  Flanges can also be custom-designed for certain applications.
Our Swivel-Ring Flanges are designed in accordance with ASME Pressure Vessel Code, unless otherwise specified.
