1. What is the primary purpose of a Pipeline Integrity Management
Program (IMP)?
A. Increase pipeline throughput
B. Reduce maintenance costs
C. Ensure safe and reliable pipeline operation
D. Comply with marketing regulations
The primary goal of an IMP is to maintain pipeline safety and
reliability, preventing leaks, ruptures, and environmental incidents.
2. Which federal agency regulates pipeline safety in the United
States?
A. EPA
B. OSHA
C. PHMSA
D. DOT
,The Pipeline and Hazardous Materials Safety Administration (PHMSA)
under the Department of Transportation regulates pipeline safety.
3. What is the first step in risk-based integrity management?
A. Corrosion monitoring
B. Hazard identification and risk assessment
C. Pressure testing
D. Leak detection
Risk-based integrity management begins with identifying hazards and
assessing risk to prioritize inspection and mitigation activities.
4. What does the acronym SCC stand for in pipeline integrity?
A. Standard Corrosion Control
B. Stress Corrosion Cracking
C. Secondary Coating Compliance
D. Structural Crack Control
Stress corrosion cracking is a type of metal degradation caused by
tensile stress and a corrosive environment.
5. Which type of inspection tool uses magnetic flux to detect
pipeline anomalies?
A. Ultrasonic testing
B. Radiographic testing
, C. Magnetic Flux Leakage (MFL)
D. Visual inspection
MFL tools detect metal loss and anomalies by inducing a magnetic
field and observing flux leakage.
6. What is the purpose of a cathodic protection system?
A. Increase flow rate
B. Prevent pipeline corrosion
C. Detect leaks
D. Strengthen pipeline joints
Cathodic protection reduces corrosion by making the pipeline a
cathode in an electrochemical cell.
7. Which of the following is considered a high-consequence area
(HCA)?
A. Remote desert
B. Population centers
C. Uninhabited forests
D. Offshore deepwater areas
HCAs are areas where a pipeline failure could result in significant
environmental, property, or human harm.
, 8. What is the typical cause of external corrosion in pipelines?
A. Internal contaminants
B. Excessive pressure
C. Soil and moisture interaction with the pipe surface
D. Weld defects
External corrosion occurs when pipelines are exposed to corrosive soils
and moisture without proper coating or cathodic protection.
9. What type of pipeline anomaly is most likely detected by
ultrasonic testing?
A. Coating disbondment
B. Wall thickness reduction and cracks
C. Soil corrosion
D. External coating damage
Ultrasonic testing sends high-frequency sound waves to measure wall
thickness and detect internal defects.
10. What is the minimum frequency for in-line inspection (ILI) in
high-consequence areas?
A. Every 20 years
B. Every 5 years
C. Every 10 years
D. Only when failure occurs
