VOL 11.03: Pressure Vessel Safety
Quality Tools/Concepts   »  
(September 19, 2020)

A pressure vessel is a closed container designed to withstand pressure, whether internal or external. The pressure may be imposed by an external source, by application of heat from a direct or indirect source or by any combination thereof. The pressure vessels are usually subjected to an internal or external pressure greater than 15psig(103 kPa).

Internal pressure in a vessel is developed from the fluid in process application. External pressure on a vessel may be imposed by an internal vacuum or pressure of the fluid between an outer jacket and vessel wall. The components of the vessel may fail, causing dangerous accidents, if the vessel cannot withstand the internal or external pressure.
