Process Temperature and Pressure Rating

Figure A-1. Maximum process temperature and pressure diagram for standard tank connections.

The tank connection consists of a tank seal, a flange(1), Tri-Clamp(2)or NPT or BSP/G threads(3). See “Ordering Information” on page A-21).

Flange mating face dimensions follow ANSI B 16.5, JIS B2220, and

EN 1092-1 standards for blind flanges. Fisher and Masoneilan flanges are also available.

Certain models of flanged Alloy and PTFE covered probes have a tank connection design with a protective plate of the same material as the probe, to prevent the 316L / EN 1.4404 SST flange from being exposed to the tank atmosphere.

The following diagrams give process temperature (maximum product temperature at the lower part of the flange) and pressure ratings for tank connections:

•Standard (Std)

•High Temperature and High Pressure (HTHP)

•High Pressure (HP)

•Cryogenic (C)

NOTE!

For standard tank connection, the final rating depends on flange and O-ring selection.

The C version can manage lower temperatures (-321 °F/-196 °C) than the Standard, HP, and HTHP versions.
