Flanged Universal Expansion Joint |
|
50 inch Through 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.
- Tabulated values are for tied joints, with butt weld ends. Performance of joints with flanged ends, and unrestrained joints, will exceed tabulated values.
- Maximum test pressure: 1.5 X rated working pressure.
- Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
- Pressure thrust load applied to adjacent pipe anchors/equipment when unrestrained expansion joints are used.
