Dear Freinds,

I am doing Saddle analysis in PV Elite. I noticed that, in Horizontal vessel analysis for testing " Hydrostatic Test Pressure at center of Vessel is giving different from the vessel design summary. so my question is how this pressure is calculated at the center of the vessel? is there any reference given any where? please reply me.

for example: for horizontal vessel 1570 mm IDX18100 mm Tan/Tan, Internal pressure is 31 barg & hydro test pressure 44.24 barg and i have used 3 Saddles, but after program run it is showing

" Hydrostatic Test Pressure at center of Vessel:10.504 bars"

Thank you,

regards,
Sameer
