- These expansion joints contain hinges or pivots which cause the unit to bend in a single plane. Normally, these units are prevented by their design from deflecting axially, either in extension or compression. Their hinge mechanisms are usually designed to accept the 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.
■ Application
- Steam, cold water, hot water, and other pipelines.
