pressure
The pressure ranges indicated can be reduced by the choice of process connection. The nominal
pressure (PN) indicated on the nameplate refers to a reference temperature of 20 °C, and of
100 °F for ASME flanges. Observe pressure-temperature dependency.
Please refer to the following standards for the pressure values permitted at higher
temperatures:
• EN 1092-1: 2001 Tab. 18
With regard to their stability-temperature property, the materials 1.4435 and 1.4404 are
grouped together under 13EO in EN 1092-1 Tab. 18. The chemical composition of the two
materials can be identical.
• ASME B 16.5a – 1998 Tab. 2-2.2 F316
• ASME B 16.5a – 1998 Tab. 2.3.8 N10276
• JIS B 2220
