Product details
Gimbal Expansion Joints which can permit angular rotation in any plane, consist of two pair of hinges affixed to a common floating gimbal ring. The Gimbal Expansion Joints are similar to Hinge type except that unlike Hinged Bellows which are limited to deflection in only one plane, Gimbal Expansion Joints can accept bending or angulations in any plane. A single bellows and gimbal hardware designed to resist pressure thrust. The gimbal expansion joint hardware operates like the universal joint on a drive shaft to accommodate angular movements in any plane. Universal Gimbaled Expansion Joints are similar to the hinged universals except that the two expansion joints are gimbal type. The advantage of this arrangement is the ability of the expansion joint to accept large lateral movements and independent angular movements in any plane. It contains two hinge pins, the axis of each being perpendicular to the other. Each set of pins is connected to each other with a central gimbal ring. It provides similar restraint and resistance to axial forces such as the pressure thrust and to shear forces as the hinge type apart from having other features like absorbing angular rotation, preventing torsion on bellows and no main anchors required.
