If the nozzle has a projection inside of the vessel, enter that length. This value is used to determine the pressure stress intensification factor from the Cers/eps graphs in Section 3 of the PD 5500 Code. All of the curves for protruding and flush nozzles are included for analysis.

The software uses the smaller of the inside projection and the thickness limit with no pad to calculate the area available in the inward nozzle. You can safely enter a large number such as six or twelve inches if the nozzle continues into the vessel a long distance.
