Notes:
- Extension movement capabilities can be increased with additional pre-compression during installation.
- Anchors should be used to resist the pressure thrust force and isolate the thermal movements between expansion joints.
- For vacuum or large pre-compressed applications, a set-back may be required to keep the expansion joint from protruding into the gas stream or touching the flow liner/baffle.
- Retaining Rings/ Backing Bars of 1/4" thickness standard. – Suggested bolt spacing at 4" centers max.
- For full product specifications and installation instructions, see SPEC 1092-1 and 1097-1 and ININ 1092-1 and 1097-1.
