What flange is Swivel Flange? The outer ring of the rotary flange (RSR) allows a 360° rotation centered on the inner ring for rapid alignment of the bolt hole with its matching standard flange. This feature is important for subsea pipeline operations, allowing divers to align bolt holes more quickly and easily.
