What they ask about
Free sample questions from API 576
Which pressure-relief valve suits incompressible service, opening by an amount proportional to how far pressure has risen?
- A. Safety Valve
- B. Relief Valve ✓
- C. Rupture Disk
- D. Pilot-operated Valve
- E. Pin-actuated Device
Liquids, being incompressible, are handled by relief valves; the amount the valve lifts normally tracks how far pressure has risen above the opening pressure. API 576, 4.2.3
What technology may be used during an on-stream inspection to identify a valve that is not seating correctly due to a thermal differential?
- A. Radiography
- B. Infrared thermography ✓
- C. Ultrasonic thickness gauging
- D. Magnetic particle testing
- E. Dye penetrant
Infrared cameras can detect the heat signature of a leaking fluid passing through a valve that should be closed. API 576, 6.4.2.1.f
A refinery is establishing a new PRD inspection program. Based on API 576, what is the primary intent of following the recommended inspection and repair practices?
- A. To minimize insurance premiums
- B. To ensure proper performance of PRDs ✓
- C. To replace all ASME Section VIII requirements
- D. To eliminate the need for engineering judgment
- E. To automate the repair process
The scope states the RP is intended to ensure the proper performance of PRDs in the owner-operator's plant. API 576, 1
