The Swivel-Ring Flange permits 360° rotation of an outer ring around a hub, to allow easy alignment of bolt holes when attaching to a mating standard flange. For subsea applications, this capability 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, API 6A or MSS SP-44.

Design Specifications

Swivel-Ring Flanges meet the requirements of API 6H and are designed in accordance with ASME Pressure Vessel Code, Section VIII, Division 2, unless otherwise specified, and applicable sections of the flange specification to which it will mate.

API Specified 6B Weld Neck Flanges have restricted bores to match standard pipe sizes and schedules. API Spec 6A Specified, 6 BX Weld Neck Flanges, have material and dimensions that conform to the requirements for full bore integral flanges. API Spec 6A does not specify overall length of 6BX Weld Neck Flanges, but instead provides dimensions of specific portions of the flange, with tolerance, that are added together, along with an undefined weld bevel, to achieve a length. Customers may specify weld neck length if required.
