Vessels used to store liquids at low pressure are normally fitted with flat end sections.This is the cheapest way of enclosing the end of a vessel.For storage of fluids at higher pressures,the ends are normally domed to reduce mechanical stresses.A number of different domed head designs are used.What is a Pressure Vessel? Uses,Fabrication, TypesPressure vessel fabrication and operation present inherent danger.So there are stringent regulations on the manufacturing of pressure vessels by engineering authorities.Types of Pressure Vessels.Hypothetically,pressure vessels can take many different shapes.However,the most common shapes are cylinders,spheres,and cones.The combination Vol.4,Issue 5,May 2015 Stress Analysis of Pressure different type of end connections by using Finite Element tool.Static structural analysis is done in order to calculate stresses in vessel.KEYWORDS Pressure Vessel,End connections,Stress analysis,FEA.I.INTRODUCTION A pressure vessel is defined as container with internal pressure,higher than atmospheric pressure.The fluid

Pressure vessels are ubiquitous in modern society and commonly go unseen by the general public.However,industrial pressure vessels are essential to the continual processing and manufacturing by industrial and commercial concerns and therefore have a direct impact on the both the economic and physical well being of society.Stress Analysis of Thin-Walled Pressure VesselsJan 15,2015 Introduction to Different Pressure Vessel Head Types#0183;Stress Analysis Thin-Walled Pressure Vessel,1.Introduction Pressure vessels are compressed gas storage tanks designed to hold gases or liquids at a pressure substantially different from the ambient pressure.They have a variety of applications in industry,including in oil refineries,nuclear reactors,gas reservoirs,etc.Strength of Pressure Vessels with Ellipsoidal HeadsHEAD Stresses in the walls of pressure vessels occur due to different types of loads,depending on the purpose of the vessel and on different influences that a vessel is subjected to during exploitation.Internal pressure has the biggest influence on the amount of stress,so all other types of loads are considered to be less important.
If a cylindrical pressure vessel is subjected to pressure,the cylindrical part and its head will tend to expand at different rates as shown in Figure 8-7.The head alone would displace radially a distance w m1 because of internal pressure,and the cylindrical portion would displace w m2 if it were not attached to the head.Semi-Elliptical (SE) Heads This elliptical shape head is designed in a 2:1 ratio,and it is also known as 2:1 head.InASME Flanged and Dished (ASME FD) Heads As the name suggests,these heads are ideal for pressure vessels designed forASME FD 60 head would need a 69 circle blank to form the head.You needMore Introduction to Different Pressure Vessel Head Types Was this helpful?People also askWhat are the different types of pressure vessel heads?What are the different types of pressure vessel heads?The Ellipsoidal Head,Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads.See the following Fig.for these heads sketches:Pressure Vessel Heads - Inspection for IndustrySelecting the most Economical Vessel Head - Chemical Introduction to Different Pressure Vessel Head Types#0183;Ellipsoidal Head,Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads.
