Single Expansion Joints – 3 1/2 Inch Nominal Diameter
3 1/2 Inch Nominal Diameter
Effective (Thrust) Area: 16.12 in2 (104 cm2)
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: For appropriate flange temperature/pressure ratings, see… catalog flange data
- 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.
