This document discusses the design of a vertical pressure vessel according to ASME standards using various software tools. The pressure vessel is designed to hold saturated steam at 435 Psi and 450F. It includes ellipsoidal heads and four nozzles of varying diameters and lengths. The vessel material is SA-51670 steel. The design is modeled in SOLIDWORKS and analyzed in ANSYS to locate stressed zones and verify stresses are below code limits. The goals are to optimize the design, study loads on the supporting skirt, and compare FEA results to manual calculations.

ABSTRACT
CONTACT
This project is on designing a
very important industrial
equipment; Pressure Vessel
which is utilized in holding gas
or liquid at a pressure that is
substantially different from the
ambient pressure.
Vertical pressure vessel is
designed according to ASME
section (VIII) division (I) on
CODEWARE COMPRESS PV
software. For 3-D modeling
SOLID WORKS has been
used.
Finally for simulation purposes
to perform FEA stress analysis
of Pressure Vessel ANSYS is
used and the results obtained
are verified with the manual
calculations.
Pressure vessels have two major types on the
basis of shape; Vertical and horizontal.
Vertical Pressure Vessel consists of a vertical
cylinder, supporting skirts or legs, two
cylinder heads and inlet/outlet nozzles.
In this project vertical Pressure Vessel is being
designed which contains a saturated steam
at 435 Psi and 450F temperature. Heads used
are ellipsoidal type. Four nozzles which have
different diameter and length are attached to
it.
Supporting skirt is also used having height of
150 inches. The material of Pressure Vessel is
SA-51670 (ASME II-D). Software used are:
COMPRESS, SOLIDWORKS & ANSYS.

INTRODUCTION
 To design a pressure vessel according to
ASME standards section VIII division I.
 To locate the critically stressed zones on the
Pressure Vessel graphically.
 To calculate stresses at different parts of the
Pressure Vessel i-e Nozzle, Cylinder heads,
joints.
 To optimize the design by changing the different
parameters of the Pressure Vessel.
 Study of load on skirt and consequently the
stresses developed on it.
OBJECTIVES CONCLUSIONS
 Vertical Pressure vessels are
suitable for the places having less
space.
 Critically stressed zones are at
nozzles joints and holes.
 For the design point of view;
temperature and pressure, the
thickness of the PV of 2.45 inches
is very optimum.
 Supporting Skirt designed for the
PV is capable of supporting weight
of PV.
 FEA analysis being performed
shows the maximum allowable
stresses on PV.
 Long Pressure Vessels are prone
to be failure due to wind & seismic
conditions.
