Texas Boiler Inspector Certification
Exam Questions And Correct Answers
(Verified Answers) With Rationales
2025|2026 Q&A
1. What is the primary purpose of a boiler inspection?
A. Improve fuel efficiency
B. Assess operator performance
C. Ensure the safe operation of the boiler
D. Reduce water usage
The main goal of inspection is to prevent hazardous conditions and
ensure the boiler operates safely.
2. According to Texas regulations, how often must high-pressure boilers
be inspected internally?
A. Every 6 months
B. Annually
C. Every 2 years
D. Every 3 years
High-pressure steam boilers require internal inspections at least once
per year.
,3. What document establishes the rules for the construction of new
boilers?
A. ASME Section II
B. NFPA 85
C. ASME Boiler and Pressure Vessel Code Section I
D. API 510
ASME Section I outlines construction requirements for power boilers.
4. What type of test is typically conducted to verify the integrity of a
repaired pressure boundary?
A. Ultrasonic Test
B. Radiographic Test
C. Hydrostatic Test
D. Magnetic Particle Test
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
D. Economizer
Safety valves release steam to maintain pressure within safe limits.
6. What is the minimum size of a safety valve discharge outlet for a 200
psi power boiler?
A. 1 inch
B. 2.5 inches
C. 3 inches
D. 4 inches
Discharge sizes are regulated based on pressure and capacity per
ASME standards.
, 7. Which of the following is not a type of non-destructive examination
(NDE)?
A. Radiographic testing
B. Magnetic particle testing
C. Ultrasonic testing
D. Destructive bend testing
Destructive tests are not NDE since they damage the component
being tested.
8. What should be checked before performing a hydrostatic test?
A. Fuel line pressure
B. Exhaust damper position
C. Temperature and pressure relief valve operation
D. Flame scanner alignment
All relief valves must be verified to avoid overpressurizing during the
test.
9. What does the acronym “NB” stamp indicate?
A. Non-boiler use
B. National Board certification
C. National Bonding
D. Nuclear Boiler code
The “NB” stamp is applied to pressure vessels registered with the
National Board.
10. What must an inspector do when they find a hazardous
condition on a boiler?
A. Note it in the inspection report only
B. Inform the operator to monitor it
C. Condemn or tag out the boiler
D. Wait until the next inspection
