- Rated cycle life is 2000 cycles per EJMA 7th edition for any non concurrent movement tabulated.
- To combine axial, lateral movements, refer to step 5 How to Specify a Single Expansion Joint
- Maximum axial extension movement is 50% of tabulated axial value.
- To obtain greater movements or cycle life refer to step 5 How to Specify a Single Expansion Joint or contact the factory.
- Catalog pressure ratings are based upon a maximum bellows temperature of 800°F. Actual operating temperature should always be specified.
- If unit is flanged, see Standard Flange Data for maximum flange pressure ratings.
- Maximum test pressure: 1 1/2 x maximum working pressure.
