🔍 Key Concepts

• Hydrostatic test procedure for water-tube boilers in 46 CFR (engineering/boiler inspection requirements) • Why water temperature matters when applying high pressure to a boiler • What condition the boiler must be in (open vs. closed up) during a pressure test

💭 Think About

• Ask yourself: During a hydrostatic test, do we want the boiler metal structure to be as stressed as during normal steaming, or do we want to minimize thermal stress? • Consider whether inspection plates and manholes are normally open for visual inspection, or closed to hold pressure for a hydro test. • Think about whether steam stops (valves) are tested under water pressure, steam pressure, or both at the same time.

✅ Before You Answer

• Verify what temperature range is normally specified for hydrostatic testing water, and why extreme hot or cold is avoided. • Check whether a boiler can be pressurized with water if inspection plates/manholes are removed, or if they must be secured. • Confirm if hydro tests are intended to involve steam pressure, or only water (hydrostatic) pressure.
