The ends of the vessel (heads) come in various shapes, each with different pressure-bearing capabilities:
Pressure vessels are the silent workhorses of modern industry. From the air compressor in your garage to the nuclear reactors powering cities, these sealed containers are designed to hold gases or liquids at pressures substantially different from the ambient atmosphere. The failure of a pressure vessel is not a simple leak; it is a catastrophic energy release comparable to a bomb. Consequently, the design of these vessels is not merely an engineering challenge—it is a legal and ethical imperative. Pressure Vessel Design Guides And Procedures
