C. To prevent pipeline failures and leaks
o o o o o
D. To reduce employee turnover
o o o
An integrity management program focuses on maintaining safe operation
o o o o o o o o
and preventing incidents through monitoring, maintenance, and risk
o o o o o o o o
assessment.
o
2. Which federal agency regulates hazardous liquid pipelines in the U.S.?
o o o o o o o o o
A. EPA
B. PHMSA
C. OSHA
D. DOE
The Pipeline and Hazardous Materials Safety Administration (PHMSA)
o o o o o o o
oversees pipeline safety standards and regulations.
o o o o o o
3. What is a hydrostatic test used to determine?
o o o o o o o
A. Flow velocity o
B. Gas composition o
C. Pressure integrity of the pipeline o o o o
D. Corrosion rate o
Hydrostatic testing checks for leaks and verifies pipeline strength by filling it
o o o o o o o o o o o
with water and applying pressure.
o o o o o
,4. Which of the following is a common cause of pipeline corrosion?
o o o o o o o o o o
A. High voltage interference
o o
B. Electrochemical reactions with the environment o o o o
C. Pipeline diameter o
D. Internal coating failure o o
Corrosion occurs when metal reacts with its environment, often due to
o o o o o o o o o o
electrochemical processes.
o o
5. What does the acronym HCA stand for in pipeline integrity management?
o o o o o o o o o o
A. Hazard Control Assessment o o
B. High Consequence Area
o o
C. Hydraulic Compression Analysis o o
D. Hazardous Chemical Area o o
HCAs are locations where pipeline failure would have significant
o o o o o o o o
consequences to health, safety, or the environment.
o o o o o o o
6. What is the main function of a cathodic protection system?
o o o o o o o o o
A. Prevent pressure surges o o
B. Detect leaks o
C. Prevent corrosion on metal surfaces o o o o
D. Strengthen weld joints o o
Cathodic protection prevents corrosion by applying a small electric current
o o o o o o o o o
to counteract natural electrochemical reactions.
o o o o o
7. Which inspection method uses sound waves to detect flaws?
o o o o o o o o
A. Radiographic testing o
B. Magnetic particle testing o o
C. Ultrasonic testing o
D. Visual inspection o
Ultrasonic testing sends high-frequency sound waves through materials to
o o o o o o o o
detect internal flaws.
o o o
8. What is a pipeline "pig"?
o o o o
A. A corrosion inhibitor
o o
B. A leak detection device
o o o
, C. A device used to clean or inspect the pipeline interior
o o o o o o o o o
D. A pressure relief valve
o o o
Pipeline pigs are tools that travel through the pipeline to clean or inspect its
o o o o o o o o o o o o o
interior condition.
o o
9. The “Smart Pig” primarily helps detect:
o o o o o
A. Flow velocity o
B. Corrosion, cracks, and deformations o o o
C. Pressure drops o
D. Valve integrity o
Smart pigs are instrumented tools that collect data on pipeline condition,
o o o o o o o o o o
identifying corrosion and anomalies.
o o o o
10. Which document must pipeline operators maintain to demonstrate
o o o o o o o
ocompliance?
A. Employee manual o
B. Invoice records o
C. Integrity management plan o o
D. Equipment calibration logs o o
An integrity management plan outlines procedures for assessing and
o o o o o o o o
omanaging pipeline risks and is required for compliance.
o o o o o o o
11. Which type of corrosion occurs when different metals are electrically
o o o o o o o o o
oconnected in an electrolyte? o o o
A. Pitting corrosion o
B. Stress corrosion cracking o o
C. Galvanic corrosion o
D. Erosion corrosion o
Galvanic corrosion happens when dissimilar metals form an electrochemical
o o o o o o o o
ocell, causing one to corrode faster.
o o o o o
12. What tool is commonly used for external corrosion direct assessment?
o o o o o o o o o
A. Drone imagery o
o o o o o o
