Swivel Flange

Swivel Flange is a spitted flange which consist of a forged outer ring, a heavy forged welding hub and a gasket, the hub can be
rotated when the flange is installed. Therefore, swivel flange is also named swivel ring flange. The flange assembly provides easy alignment of the bolt holes during makeup to a WN flange or other flange.

The outer 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. These versatile flanges are utilized in many applications and are used extensively in offshore piping where they solve the issues associated with the alignment of bolt holes during subsea flange installation.
