What term describes the maximum safe working pressure of a vessel’s equipment?

The term that describes the maximum safe working pressure of a vessel’s equipment is "Design pressure." Design pressure refers specifically to the maximum pressure that the equipment is designed to withstand, ensuring safety during operation. This value is established during the design phase and takes into consideration factors like material strength, safety factors, and potential operating conditions. It is crucial for the safe operation of pressure vessels, as exceeding this pressure can lead to failure and catastrophic results.

Other terms have different meanings in the context of pressure vessels. Operating pressure refers to the pressure at which the vessel is typically operated during normal conditions, which is generally lower than the design pressure. Breakdown pressure is not a standard term in vessel operation and does not specifically relate to safe working limits. Test pressure is the pressure applied during testing to ensure structural integrity and safety, often exceeding design pressure to verify performance but not representing the maximum safe working condition during regular operation.
