What is a Pressure Vessel A pressure vessel is a closed leak-tight container (normally cylindrical or spherical) designed to hold fluids (i.e, gases or liquids) at a pressure substantially different (higher or lower) from the ambient pressure. They are usually made from carbon steel or stainless steel and assembled from plates by welding method.
Pressure Vessel Design Formula 1 t = thickness of the shell 2 P = internal pressure 3 D = diameter of the shell 4 σ = tensile stress
The design of pressure vessels must be done with utmost care as these operate under immense pressure. A ruptured pressure vessel can cause serious irreversible harm to mankind and properties. Normally the ASME Sec VIII code governs the design of pressure vessels. Type of loading (wind load/seismic loading/snow loading)
