Rotating flange

The outer ring of the rotating flange allows 360 ° rotation centered on the inner ring to align the bolt hole with the matched standard flange adjustment. This characteristic is very important for subsea pipeline operation. It can make divers easily align bolt holes.

Rotating flange can be designed for any size and pressure rating to meet the requirements of any recognized flange specification and gasket, such as ASME B16.5 or MSS sp-44. Non standard rotating ring flange can also be designed according to customer requirements for some applications, such as cladding treatment of inner ring or PTFE spraying treatment of flange surface, etc
