INTRODUCTION:

Pressure Vessels are huge closed containers that can withstand high pressure or temperature gases

or fluids, without any leakage. Pressure vessels are available in various shapes and sizes depending

on the requirements of the industries. Despite of the theoretical assumptions, most of the pressure

vessels installed today are mainly in cylindrical or spherical. It becomes harder and more expensive

for the manufacturing of the pressure vessels in complicated shapes. These thin walled vessels

have closed heads which are either spherical or conical in shapes. For a longer life span of the

vessels, these are made with steel which has a very high impact and corrosion resistances. Pressure

vessels are manufactured to hold a specific value of pressure or temperature, known as ‘design

pressure’ or ‘design temperature’.

Today pressure vessels are a part and parcel of both private and public industrial sectors. The

applications of pressure vessels ranges from small drinking cans to huge distilling towers. Diving

gas tanks, compression chambers in mining industries and submarines, pressure vessels in

petrochemical and nuclear plants, pneumatic and hydraulic reservoirs in co-operated in space

ships, etc are also some of the example where pressure vessels are installed and functional. Due to

versatile applications of the pressure vessels engineers maintains regular inspections on the

pressure vessels so that it is safe for the people around it. As a result the designing and analysis of

the vessels are conducted with respect to numerous design codes and standards accepted

internationally. The three main factors that can affect the life of the vessels are the design (shape)

for the vessel, the material used to manufacture and the stress and strain that occurs in the vessel.
