Swivel-Ring Flange

Swivel-Ring Flange

The Swivel-Ring Flange assembly provides easy alignment of the bolt holes during makeup to a common flange such as those defined by ASME B16.5, MSS SP-44 and API 6A.

Alignment is an important and critical feature when bolting subsea pipeline flanges together. The outer ring flange of the Swivel-Ring Flange assembly is held in position by a retainer ring that freely rotates around the inner weld-neck hub for quickly positioning the bolt holes of the two joining flanges.
