Hinged Pipe Expansion Joint
Hinged Pipe 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 pipe expansion joint, relieving the piping designer of having to provide additional supports and anchors required by the Single type.
Hinged Expansion Joint Extended Information
Hinged Pipe 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 pipe expansion joint, relieving the piping designer of having to provide additional supports and anchors required by the Single type. Some hinge types can be provided with hinge pin holes which are slotted to permit limited axial travel. These "slotted hinge" types will not resist pressure thrust forces, and anchoring must be provided. This catalog only depicts the fully restrained hinged type. If axial travel is desired, the piping designer should clearly state that the slotted hinge type is wanted in the design requirements, and he should provide for pressure thrust anchoring. On the other hand, if the full axial restraint of the hinged type is desired, the piping designer should understand that there is no allowance in the expansion joint for any axial travel, including none for any installation misalignment.
