How to Delimit the Pressure Vessel?
The factors that should be considered in dividing the boundaries of pressure vessels mainly include the possibility of accidents and the damage level of accidents. At present, there is no uniform regulation on the boundary scope of pressure vessels in the world. Generally speaking, when a pressure vessel explodes, the degree of harm is related to the working medium state, working pressure and the volume of the vessel. If the working medium is a pressure container of liquid, as the compressibility of the liquid is extremely small, the expansion force released is correspondingly small when the container is blasted, thus the degree of harm is also small.
Or if the working medium is a pressure vessel of gas, because the gas has great compressibility, the expansion force is correspondingly large when the vessel is blasted, that is, the energy released instantaneously is great, and the degree of harm is great; in addition to considering the state of the working medium, the factors of working pressure and volume of the container should be considered when dividing the boundary of the pressure vessel.
