|| || || || || || || ||



new boilers?
|| ||



A. ASME Section II || ||



B. NFPA 85 ||

Hydrostatic tests are standard for pressure boundary integrity
|| || || || || || ||



||verification after repairs. || ||




5. Which device prevents overpressure in a boiler?
|| || || || || ||



A. Water level gauge || ||



B. Blowdown valve ||



C. Safety valve ||
