According to the Code of Federal Regulations (46 CFR) for General Cargo Vessels, what determines the maximum allowable pressure that can be carried in a steam boiler?
• 46 CFR requirements for steam boilers on general cargo vessels • Difference between design limits vs. operational settings (like safety valves or inspections) • Role of nameplates, tests, and certificates in defining boiler limits
• Which item represents the boiler’s original engineered design limit that should never be exceeded? • Are hydrostatic tests and safety valve settings usually set above or at the normal working pressure? What is their purpose? • Does the certificate of inspection usually create the limit or recognize/record a limit set somewhere else?
• Identify which choice reflects the permanent, manufacturer-stamped limit on the boiler itself. • Think about what the hydrostatic test is used for and whether it’s normally higher or lower than working pressure. • Consider whether the certificate of inspection depends on information that already exists on the boiler.
