Pressure Vessels
Pressure Vessels A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure Pressure vessels can be dangerous, and fatal accidents have occurred in the history during their development and operation. So extra care is taken while designing pressure vessel Safety Feature of Pressure Vessels Leak Before burst: Pressure vessels are designed such that a crack in the vessel grow through the wall, allowing containing fluid to escape Safety value: Allow containing fluid to escape if pressure rises above set point Stresses in Pressure Vessels When a thin – walled cylinder is subjected to internal pressure, two mutually perpendicular principal stresses set up in the cylinder materials, namely 1. Longitudinal stress 2. Circumferential or hoop stress ...
