Probe ⌀22 mm (0.87 in) including insulation
–1 to 50 bar (–14.5 to 725 psi)
Refer to the following standards for the pressure values permitted at higher temperatures:
• EN 1092-1: 2005 Table, Appendix G2
With regard to its resistance and temperature property, the material 1.4435 is identical
to 1.4404 (AISI 316L) which is grouped under 13E0 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
The lowest value from the derating curves of the device and the selected flange applies.
