internal piping has mineral deposits
The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
Use water for testing.
there are many factors to be considered to achieve desired temps. when using steam as a heating source. pressure and temp. are very critical due to expansion of the vessel and the piping.
Certified Pressure Vessel
piping rated for 250 PSI OWG
The answer depends on the pressure vessel.
When water freezes in an enclosed vessel, it expands and exerts pressure on the vessel walls. This pressure depends on factors such as the volume of water, rate of freezing, and strength of the vessel. Generally, this can lead to the vessel cracking or bursting if the pressure becomes too high.

The pressure piping alternative test method is the service test for piping system. The service test is however, only applicable to specific cases.
A vessel implodes when the pressure inside the vessel becomes greater than the pressure outside, causing it to collapse inward. Factors that contribute to this phenomenon include a sudden change in pressure, structural weaknesses in the vessel, and the material properties of the vessel.
