Pressure Vessels

Pressure Vessels are used in refineries, chemical plants, power plants, and other process. A pressure vessel is a container used to hold gases or liquids at different temperature from ambient pressure.

The stability of a pressure vessel is very important. Its not structurally sound may leak or even burst under pressure depending on the type of liquid or gas inside the tank,

leaks can cause poisoning, fire, or suffocation.Types of pressure vessels are, Thin- walled,  storage tanks, and transportable containers.

Thin-walled vessels -10 times or more the thickness of the wall.

Storage tanks – kind of super thin-walled vessel. Transportation vessels- are mass produced thin-walled vessels. Thick-walled vessel -diameter that is less than 10 times the thickness of the wall which is the least common type of pressure vessels.

Material used in this pressure vessels are steel, aluminium, other metals, carbon, polymers. Design and analysis of Pressure Vessels (Tall Columns, Vertical Pressure Vessels, Horizontal Pressure Vessels, Spherical Vessels, Reactors etc.) based on ASME Boiler & Pressure Vessel Code, Section VIII, Div. – 1, Div. – 2 and Div. – 3.

Manufacturing Process

Forming-  In this process size and shapes are be changed. There are Hot, warm, cold formings are used.

Pressing- pressing the machine related to the needs.

Spinning- Shape the Heads which means the ends of the pressure vessels.

Bending- Bending or rolling process is done here.

Welding- Two or more materials are joined by melting both materials.

Post Weld Heat Treatment- To make more strong by heating the product in furnace.

Assembly- Process of joining

Painting- Protect from corrosion
