How to control the working pressure of a boiler - Quora
Most modern boilers are not controlled by an ON/OFF switch as they did in the past if automatic. A pressure switch with a cut out at high pressure and a cut-in at some span below the high cut-off is a tad old-fashioned, though still used in domest

Pressurizing the boiler to 5 psig with a nitrogen blanket system will ensure that oxygen will not be introduced into the boiler. Cold storage is recommended using the wet procedures above; however, if dry storage is necessary, make sure that ample quantities of desiccant are placed in the drums and that the waterside is closed up tight.

Cavitation - Wikipedia
Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery. These shock
