Swivel Flange | Rotating / Adjustable Flange | Pipeline & Piping Applications | Class 150–2500
Elite Swivel Flanges are engineered flange assemblies designed to allow rotational alignment of the bolt-hole pattern during installation while maintaining a fixed connection to the pipe or fitting. The rotating flange ring can be oriented independently around the pipe axis, making installation easier where precise bolt-hole alignment is difficult.
Swivel Flanges are particularly useful in pipeline, offshore, marine, oil & gas, petrochemical and process piping systems, where installation flexibility, alignment and reduced field assembly time are important.

Material selection is based on operating pressure, temperature, process fluid, corrosion conditions, mechanical requirements and applicable project specifications.
Rotating Flange Ring
The outer flange ring rotates around the fixed hub, allowing the bolt holes to be aligned with the mating flange without rotating the connected pipe.
Fixed Hub
The hub provides the pipe connection and transfers pressure and mechanical loads from the flange assembly into the piping system.
Welded Swivel Flange
The hub is welded to the pipe while the flange ring remains free to rotate for installation alignment.
RTJ Swivel Flange
Available for applications requiring a ring-type joint sealing arrangement where applicable.
RF Swivel Flange
Raised-face configuration for conventional gasketed flange connections.
