A Super Duplex S32760 swivel ring flange is a flange with a rotating ring that allows bolt holes to be aligned after welding, made from Super Duplex S32760 to ASTM A182 F55. Swivel ring flanges speed up subsea and offshore tie-ins and riser connections, where rotating the whole pipe to line up bolt holes is not possible.
