Pressure Vessels Introduction - Chemical Engineering World

For vessels subjected to internal pressure, the design pressure is usually fixed at 110% of the normal operating pressure. In calculating design pressure at any point in the vessel the head due to operating liquid, catalyst etc. has also to be considered. Vessels operating under vacuum are generally designed for full vacuum conditions.
