Notes:

  1. Contact General Rubber with your design conditions and we will provide a detailed drawing with our proposal.
  2. Anchors should be used to resist the pressure thrust force and isolate the thermal movements between expansion joints.
  3. 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.
  4. Retaining Rings/ Backing Bars of 1/4" thickness standard. – Suggested bolt spacing at 4" centers max.
  5. For full product specifications and installation instructions, see SPEC 1098-1 and ININ 1098-1.
