ASME Formulas Used
Cylindrical Shell (UG-27):
t = PR/(SE - 0.6P)
P = pressure, R = radius, S = stress, E = efficiency
2:1 Ellipsoidal Head (UG-32):
t = PD/(2SE - 0.2P)
Torispherical Head (UG-32):
t = 0.885PL/(SE - 0.1P)
Hemispherical Head (UG-32):
t = PL/(2SE - 0.2P)
Design Notes
- ⚠ High utilization - consider increasing thickness
- • Full radiography (E=1.0) reduces thickness by 18%
- • Add nozzle reinforcement per UG-37
- • Check external pressure per UG-28 if applicable
- • Weight excludes nozzles, internals, insulation
