Hinged or Angular Expansion Joints

Angular bellows incorporate a hinge assembly so as to allow angulation in a single plane. Hinged bellows expansion joints are predominantly used in combination with other hinged or gimbal expansion joints to create ‘2-pin’ or ‘3-pin’ systems, by effectively converting relatively large amounts of axial movement in to relatively small amounts of angulation.
