Bottom Head
Elastic Modulus from Chart: HA-4 at 38 C : 0.19305E+09 KPa.
Results for Maximum Allowable External Pressure (MAEP):


EMAP = B/ (Ro/t) = 63.6514 / 134.9286 = 471.7141 KPa.

Shell
Elastic Modulus from Chart: HA-4 at 38 C : 0.19305E+09 KPa.
Results for Maximum Allowable External Pressure (MAEP):


EMAP = (4*B) / (3*(D/t)) = (4*58.2298) / (3*127.0000) = 611.3009 KPa.


EMAP = (4*B) / (3*(D/t)) = (4*6.5834) / (3*127.0000) = 69.1126 KPa.

Top Head
Elastic Modulus from Chart: HA-4 at 38 C : 0.19305E+09 KPa.
Results for Maximum Allowable External Pressure (MAEP):


EMAP = B/ (Ro/t) = 63.6514 / 134.9286 = 471.7141 KPa.

Nozzle Calculation Summary


Min. - Nozzles 1115.38 H1/H2-150
Min. Shell & Flgs 1082.35 10 20 1115.01
Computed Vessel M.A.W.P 1082.35 KPa.
[*] - This was a small opening and the areas were not computed or the MAWP of this connection could not be computed because the longitudinal bending stress was greater than the hoop stress.
Note: MAWPs (Internal Case) shown above are at the high point.


Check the Spatial Relationship between the Nozzles


The Nozzle spacing is computed by the following:
= Sqrt ( 112 + 1c2 ) where
11 - Arc length along the inside vessel surface in the long. direction.
1c - Arc length along the inside vessel surface in the circ. direction.
