A swivel ring flange (SRF) is a two piece constructed flange used extensively for offshore pipelines and offshore industry applications.
A swivel ring flange has a heavy forged welding hub that is fixed to a forged ring that can be rotated to serve as a mating flange to a weld neck or another flange. In a swivel ring flange, the rotating ring is held on by the welding hub that is in turn secured by a retaining ring.

Swivel ring flanges are favored because they do not cause any problems in the alignment of bolt holes during sub-sea flange installation. Swivel ring flanges are available in various metals and specifications, including class 150 to class 2500 specifications and from 1 inch to 60 inches in diameter. These flanges are readily mated to any standard welded neck flange and are very similar to ASME / ANSI B 16.5 and MSS-SP44 standard flanges.
Swivel ring flanges are constructed using a specific grade of carbon steel or stainless steel having ASTM A105 specifications with a minimum yield of 42,000 psi pressure. Some extra thickness is provided at the welding end. These flanges are also manufactured using superior grade materials such as A694 or A707.
The SRF utilizes a spring steel retainer ring to capture the rotating flange component of the connector, thus eliminating welded retainers and permitting the removal of the retainer ring. This also makes it possible to clean and lubricate the swivel ring interface between the hub and flange after fabrication and coating to ensure easy rotation during installation
Stock inventory sizes are available from 2″ to 24″ for immediate delivery. Additional sizes available upon request.
Swivel-ring flanges are used extensively in the offshore industries and for subsea applications. Kingmetal can manufacture and supply swivel-ring flanges to exacting standards and they can be designed to suit any pressure rating. (The pressure-temperature ratings and basic dimensions (OD - bolt circle - facing - number and size of bolts) of Swivel Ring Flanges, in Class 150 through Class 2500, are identical to ASME/ANSI B16.5 and MSS-SP44 Flanges and will readily mate to a standard weld neck flange. Ring type joints (RTJ), raised face, flat face and other facings are furnished as required. Sizes up through 60" including flanges to mate to ASME B16.47 dimensions are available.)
One of the main features of a swivel-ring flange is that it allows a 360 degree rotation of an outer ring around a hub and this enables easy alignment of bolt holes when attaching to a standard flange. This is particularly important for subsea applications when there is only one diver available to align and set up the flange connection.
At Kingmetal we can design swivel-ring flanges for a variety of size and pressure ratings; standard specifications being API 6A, ASME B16.5 and MSS SP-44. We can also custom-design swivel-ring flanges based on your specific requirements. ...
