Hi:
Just North of me there's a museum that has working live steam boilers and many
engines.
Every year they pressure test everything carrying steam prior to the annual
steam up.
The test is simply to fill the boiler (or other equipment) with water in such a way that there is no trapped air and
then pressurize the system to say 2X or 3X the operating pressure.
If there's a weak spot as soon as it starts to move the pressure drops very quickly since water does not compress and so
there's minimal danger.
I don't see why they could not do room temperature pressure test using water
prior to every run?
Have Fun,
Brooke Clarke
