1. What is the primary purpose of inspecting a pressure vessel?
A. To improve appearance
B. To increase production speed
C. To ensure safe operation and compliance with applicable codes
D. To reduce fuel costs
Answer: C
Rationale: Pressure vessel inspections verify structural integrity, safe
operation, and compliance with applicable safety codes to prevent failures
and protect personnel and property.
, 2. Which ASME Code Section primarily governs the construction of
pressure vessels?
A. Section I
B. Section V
C. Section VIII
D. Section IX
Answer: C
Rationale: ASME Section VIII contains the rules for the design, fabrication,
inspection, testing, and certification of pressure vessels.
3. Which organization publishes the National Board Inspection Code
(NBIC)?
A. OSHA
B. ANSI
C. National Board of Boiler and Pressure Vessel Inspectors
D. EPA
Answer: C
Rationale: The NBIC provides nationally recognized requirements for
installation, inspection, repair, and alteration of pressure-retaining
equipment.
, 4. What is the primary purpose of a pressure relief valve?
A. Increase vessel pressure
B. Measure pressure
C. Prevent overpressure conditions
D. Control vessel temperature
Answer: C
Rationale: Relief valves automatically release pressure when system
pressure exceeds safe operating limits.
5. The Maximum Allowable Working Pressure (MAWP) is determined by:
A. The vessel owner
B. The inspector
C. The weakest pressure-retaining component under specified
conditions
D. The operating supervisor
Answer: C
Rationale: MAWP is based on the vessel's weakest component considering
design conditions and applicable code requirements.
, 6. Which instrument is commonly used to measure vessel wall thickness?
A. Micrometer
B. Pressure gauge
C. Ultrasonic thickness gauge
D. Thermocouple
Answer: C
Rationale: Ultrasonic testing accurately measures remaining wall thickness
without damaging the vessel.
7. Corrosion generally results in:
A. Increased wall thickness
B. Improved strength
C. Reduced wall thickness
D. Increased ductility
Answer: C
Rationale: Corrosion removes metal, reducing thickness and pressure-
retaining capability.
