Hinged Expansion Joints

Hinged Expansion Joints contain hinges or pivots which allow the unit to bend in a single plane. These units are designed to restrict axial deflection, either in extension or compression. The hinge mechanism is typically designed to accept full pressure thrust. Also, because of the hinge mechanism's design, shear loads, such as from the weight of adjacent piping, can be accepted by this expansion joint, relieving the piping designer of having to provide additional supports and anchors required by the Single type.

• Angular motion in all planes
• Positive control over movement
• Eliminates pressure thrust forces
• Transmits external loads
• Bolsters dead weight
• Prevents torsion on bellows
• No main anchors required
• Minimum guiding required
• Low forces on piping system
• Most efficient in absorbing thermal deflections
