🔍 Key Concepts

• 46 CFR Part 52 – Power Boilers construction requirements for safety valves • Rules about threaded inlets vs. flanged inlets on larger safety valves • Requirements for gagging safety valves during hydrostatic tests and limits on popping/reseating pressure tolerances

💭 Think About

• Look at each option and ask: Is this a specific requirement you have seen in the boiler/safety valve sections of 46 CFR, or does it sound like an unsafe workaround? • Consider why the Coast Guard is strict about how safety valves are attached and how/when they can be gagged. Which practices would clearly defeat the purpose of a safety valve in normal operation? • Think about typical allowed tolerances for set pressures on safety valves. Does a very tight or very loose percentage seem more realistic for safe, practical operation?

✅ Before You Answer

• Verify in 46 CFR whether threaded inlets over 2 inches are prohibited for boiler safety valves. • Confirm if gagging by a set screw through the cap is ever mentioned as an acceptable method, and under what exact conditions (if any). • Check the specific allowable percentage variation between set (popping) pressure and reseating pressure for propulsion boiler safety valves in 46 CFR.
