1. What is the primary purpose of a cathodic protection system in
pipeline transportation?
A. To prevent over-pressurization
B. To prevent corrosion
C. To detect leaks
D. To increase flow efficiency
B. To prevent corrosion
Cathodic protection is used to reduce or eliminate the corrosion of
metal surfaces in pipelines by making them the cathode of an
electrochemical cell.
2. Which federal regulation governs the safety standards for hazardous
liquid pipelines?
A. 29 CFR Part 1926
B. 49 CFR Part 195
C. 40 CFR Part 112
D. 49 CFR Part 192
, B. 49 CFR Part 195
49 CFR Part 195 sets forth the safety regulations for the
transportation of hazardous liquids by pipeline.
3. What type of pipeline inspection tool uses magnetic flux leakage
technology?
A. PIG
B. Thermocouple
C. Ultrasonic sensor
D. Leak detector
A. PIG
Magnetic flux leakage (MFL) tools are a type of intelligent pig used
to detect corrosion and pitting in steel pipelines.
4. The term "Right-of-Way" (ROW) in pipeline operations refers to:
A. Government authority to build pipelines
B. Landowner compensation
C. Legal easement for pipeline use
D. Construction permit
C. Legal easement for pipeline use
A ROW is a legal right to use someone else's land for a specific
purpose such as pipeline installation and maintenance.
5. Which of the following best describes SCADA in pipeline operations?
A. Security Control Against Damage Alerts
B. Supervisory Control and Data Acquisition
C. Safety Control and Data Alarm
D. Strategic Control Automated Device
B. Supervisory Control and Data Acquisition
SCADA systems are used for remote monitoring and control of
pipeline operations.
,6. A hydrostatic test is conducted to:
A. Check the chemical composition of the pipeline
B. Test pressure integrity of the pipeline
C. Measure flow rate
D. Detect gas leaks
B. Test pressure integrity of the pipeline
Hydrostatic testing involves filling the pipeline with water and
pressurizing it to test for leaks and structural integrity.
7. Which valve type is most commonly used in pipelines for quick
shutoff?
A. Gate valve
B. Butterfly valve
C. Ball valve
D. Check valve
C. Ball valve
Ball valves provide quick shutoff and are widely used in pipeline
systems for their reliability.
8. What does a pipeline marker typically indicate?
A. Pipeline ownership and location
B. Pipe diameter
C. Type of weld
D. Thickness of coating
A. Pipeline ownership and location
Pipeline markers help identify the presence, contents, and owner of
the pipeline, improving safety and awareness.
9. Which component prevents reverse flow in a pipeline system?
A. Gate valve
B. Relief valve
C. Check valve
, D. Globe valve
C. Check valve
Check valves allow flow in one direction and prevent backflow, which
is critical in pipeline systems.
10. What is the minimum depth required for a buried transmission
pipeline under roadways in most jurisdictions?
A. 12 inches
B. 18 inches
C. 24 inches
D. 36 inches
D. 36 inches
To ensure safety and prevent damage from surface activities,
pipelines are typically buried at least 36 inches deep under roads.
11. What is a "smart pig" used for in pipeline maintenance?
A. Insulation
B. Leak detection
C. Internal inspection
D. Emergency response
C. Internal inspection
Smart pigs are inspection tools inserted into pipelines to detect
corrosion, deformation, and other defects.
12. A pipeline’s maximum allowable operating pressure (MAOP) is
determined by:
A. Pipe color and coating
B. Pipe material and wall thickness
C. Pipe burial depth
D. Pigging frequency
B. Pipe material and wall thickness
