Pressure/temperature limits
Steam saturation curve
Pressure bar g
The product must not be used in this region.
Notes: 1. If flange connections are fitted then these will limit the maximum design conditions of the pipeline connector. 2. The maximum operating limits of the complete assembly will be dictated by the steam trap of choice. Reference the specific steam trap technical information sheet for its 'Pressure / temperature limits'.
Body design conditions
ASME class 600
99.3 bar g @ 38 ° C
PMA Maximum allowable pressure
425 ° C @ 56 bar g
TMA Maximum allowable temperature
PMO Maximum operating pressure for saturated steam service
62 bar g
