WebNov 1, 2024 · Maximum operating pressure is usually the high trip pressure of the system. Hydrotest Pressure - hydrostest pressure is the required pressure that pressurized systems such as vessels, pipelines, plumbing, gas cylinders, boilers, tanks can be tested for strength and leak. Hydrotest pressure is 1.5 * (design pressure) as a rule of thumb. WebAll we can assume is that, by maximum operating pressure or working pressure, the maximum pressure that can occur under normal operating/working conditions is meant. However, it is also possible that it is understood to be the maximum pressure that could occur – including the event of a failure.
