60 inch, 66 inch, 72 inch Nominal Diameter

Notes:

Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
To combine axial, lateral and angular movements, please refer to the how to order section.
To increase cycle life or movements, please refer to graph on cycle life.
Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
Maximum test pressure: 1.5 X rated working pressure.
Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.
Overall lengths and weights for unrestrained expansion joints only. Consult factory for information regarding tied, hinged, or gimbal expansion joints.
Pressure thrust load applied to adjacent pipe anchors/equipment when unrestrained expansion joints are used.
