Product Description
The 8in Toroidal Swivel allows for the transfer of fluids from a geostationary part to the rotating part (or vice versa) of a turret mounted on FPSO/FSO. , The swivel consists of a stator and a rotor enclosing a toroidal flow path, with a bearing system allowing the relative rotation between the stator and the rotor. , Turret piping is connected to Techlok type flanges located on the stator pipes and rotor. , A sealing system comprising of primary, secondary and tertiary seals ensures leakage is maintained within an acceptable limit, and also allows for the control/monitoring of any leakage, and to incorporate a leak recuperation system.
