Notes
- Special size and length can be customized.
- 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.
- Installed parts should be inspected regularly in pipelines or equipment carrying fluids at elevated temperature or pressure.
- OEM and ODM service is available where applicable.
