A.1.5 Process temperature and pressure rating
Process temperature
Figure A-2. Max. Rating, Standard Tank Connections
Note
The maximum process temperature is at the lower part of the flange.
Final rating depends on flange and O-ring selection. Ta bl e A -1 gives the temperature ranges for
standard tank seals with different O-ring materials.
Table A-1. Temperature Ranges for Standard Tank Seals with Different O-ring Materials
Note
Always check the chemical compatibility of the o-ring material with your application. If the
o-ring material is not compatible with its chemical environment, the o-ring may eventually
malfunction.
