Operating
| Temperatures: | upto 400° : AM350 |
| Above 400°: Haste Alloy C-276 & INCONEL-718 | |
| Pressure: | Under 10kg/Up to 9.8bar: Single Ply |
| Above 10kg/Up to 29.4bar: Double Ply | |
| Speed: | Up to 5000 fpm or 25 m/s |
* These operating limits are non-concurrent. In general, an incease in the seal size, or temperature, or rotating speed can reduce the maximum operating pressure limit of the metal bellow component.
