Notes
- Higher temperatures affect movement and pressure. Rated values should be reduced accordingly as temperature increases.
- Pressures shown are recommended operating values; test pressure is 1.5 times operating pressure.
- Runtai expansion joints may operate in pipelines or equipment carrying fluids at elevated temperature or pressure. Installed parts should be inspected regularly.
- For other applicable fluids, please consult the supplier or manufacturer.
