Louisiana [LA] 7-23 Industrial Pipe
Work and Insulation Practice Exam
Newest 2026.
1. What is the primary purpose of industrial pipe insulation?
A. Improve appearance
B. Prevent corrosion only
C. Control heat loss or gain
D. Increase pipe pressure
Answer: C
Insulation is primarily used to reduce heat transfer, improving energy
efficiency and protecting personnel.
2. Which material is commonly used for high-temperature pipe
insulation?
A. Fiberglass
B. Polyethylene foam
C. Rubber
D. PVC
Answer: A
Fiberglass withstands high temperatures and is widely used in industrial
settings.
3. ASME B31.3 primarily governs:
,A. Residential plumbing
B. Process piping
C. Electrical wiring
D. Roofing systems
Answer: B
ASME B31.3 applies to process piping systems found in industrial plants.
4. The main hazard of uninsulated steam lines is:
A. Pipe expansion
B. Increased pressure
C. Burn injury
D. Noise
Answer: C
Steam lines can reach extremely high temperatures and pose serious burn
hazards.
5. What tool is commonly used to cut insulation board?
A. Pipe wrench
B. Insulation knife
C. Torque wrench
D. Reamer
Answer: B
An insulation knife is specifically designed for cutting fibrous insulation
materials.
6. What does “cryogenic insulation” protect against?
, A. High heat
B. Extreme cold
C. Fire spread
D. Corrosion only
Answer: B
Cryogenic insulation is designed for extremely low-temperature systems.
7. Which personal protective equipment (PPE) is essential when
handling fiberglass?
A. Steel-toe boots
B. Respirator and gloves
C. Welding hood
D. Face shield only
Answer: B
Fiberglass fibers can irritate lungs and skin; gloves and respirators reduce
exposure.
8. The R-value measures:
A. Pressure rating
B. Heat resistance
C. Pipe diameter
D. Density
Answer: B
R-value measures thermal resistance — higher values mean better insulation
performance.
9. What type of joint is commonly used in steel pipe systems?
