Abstract

Abstract – Pressure vessel is a structure which used for fluida storage wheter in gas or liquid form in
many kind of industries. Referred as pressure vessel because the pressure and temperature of the
fluida inside the pressure vessel is different compared to pressure and temperature of atmosphere
outside of pressure vessel. This research started with calculating the plate thickness in every section
based on internal and external pressure consideration. After that, the next step is calculating the
maximum deflection due to wind load and required plate thickness due to seismic load. Finally, the
last step is calculating the stress value that occurs in pressure vessel using hand calculation and
ANSYS method.The result shows that the largest required thickness based on internal and external
pressure is 0,875 in and 0,1875 in for the smallest. For maximum deflection calculation, the result is
0,576 in based on Henry H. Bednar method and 4,09 in based on Dennis R. Moss method. In stress
analysis using hand calculation method, the largest result is 7.416,38 psi and 1.870,44 psi for the
smallest. On the other hand, the largest value of the stress analysis using ANSYS method is 7.832,76
psi and 1.994,99 psi for the smallest.
