What is the purpose of a nozzle on a pressure vessel shell?

The purpose of a nozzle on a pressure vessel shell is to serve as a connection point for various fittings. Nozzles are critical components that allow for the integration of different systems and functionalities within the pressure vessel. This can include the connection of pipes, valves, and instruments that are necessary for the operation, maintenance, and monitoring of the vessel.

Nozzles can be used to attach fittings that might lead to other equipment, such as pumps or other vessels. Each fitting can serve a specific role, whether it be for input or output, maintenance access, or instrumentation. By properly integrating nozzles into the design of a pressure vessel, operators can facilitate the flow of fluids into and out of the vessel, ensuring efficient and safe operation.

While nozzles can certainly accommodate connections for gauges, feed water piping, and safety valves, their primary function lies in serving as versatile attachment points for fittings. This makes them essential for the overall functionality of the pressure vessel system, contributing to its operational efficiency and safety management.
