Single Expansion Joints

This is the simplest expansion joint available and consists of a single bellows element and end connections. This expansion joint will deflect in any mode listed under Bellows Deflections, and is usually the first considered in system design. The Single Unrestrained Expansion Joint will require the most control of the adjacent piping with respect to anchors and guiding. The Single Unrestrained Expansion Joint will not control the movement of the piping in any direction. Proper anchoring and guiding must be used to control the piping and restrict the movement to only that specified for the expansion joint design. This expansion joint will not resist deflections with any force other than the spring force of the bellows. This expansion joint will not resist the pressure thrust force along the axis of the bellows. This force must be handled by the use of main and directional anchors.
