Operating conditions: Process
Process temperature range /
Process pressure limits
Note!
The specific range may be reduced by the selected process condition. The pressure rating (PN)
specified on the flanges refers to a reference temperature of 20 °C (68 °F), for ASME flanges to
100 °F. Observe pressure temperature dependency.
The pressure values permitted at higher temperatures can be found in the following standards:
• EN1092-1: 2001 Tab.18
With regard to their temperature stability properties, the materials 1.4404 and 1.4435 are
grouped under 13E0 in EN1092-1 Tab.18. The chemical composition of the two materials can
be identical.
• ASME B16.5a - 1998 Tab. 2-2.2 F316
• ASME B16.5a - 1998 Tab. 2.3.8 N10276
• JIS B 2220
