When designing and calculating a pressure vessel, one of the most critical variables to consider is the pressure differential the shell will undergo to determine whether it will have a thick or thin wall. The thickness of the shell will depend mainly on the pressure differential and the stresses to which it will be subjected.
Pressure vessels are generally thick walls when their thickness exceeds one-tenth of their average radius. Thick wall pressure vessel design aims for internal pressure applications, i.e., when the internal pressure is higher than the external pressure. For example, thick wall cylinders are used for the barrels or barrels of firearms.
