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.
