Rotary flange
Rotary flange
1. The rotary flange is mainly used for connection of submarine and underwater pipelines. The outer ring of the rotary flange allows 360° rotation centering on the inner ring to quickly align the bolt hole of the corresponding standard flange. This feature is vital to submarine pipeline operation. It can make the diver align the bolt hole quickly and conveniently.
The rotary flange can be designed for any dimension and pressure rating to meet requirements of any recognized flange specification and washer, such as ASME B16.5 or MSS SP-44. Non-standard rotary flanges for special application can be designed according to the requirements of the customer, such as cladding welding processing of the inner ring or the PTFE coating on the flange surface.
The design specification of the rotary flange: unless otherwise specified, the rotary flange shall be designed according to the requirements of API, Volume II, Chapter VIII of ASME Pressure Vessel Code and the corresponding flange specification.
