Gimble Expansion Joint

Pair of two hinges & pin or pivot whose axis are perpendicular to each other are connected to a floating gimbaled-ring.

Advantage of absorbing pressure thrust, supporting the dead weight of the system, transmitting loads through the gimbaled structure, preventing torsion & reduce forces on system.

Applied to complex piping system were proper anchoring & guiding may not be feasible.

These joints are capable of absorbing angular motion in all planes.
