, 1. What is the primary goal of a pipeline integrity management program?
A. To increase production capacity
B. To minimize inspection costs
C. To prevent pipeline failures and leaks
D. To reduce employee turnover
** Verified explanation **
An integrity management program focuses on maintaining safe operation and
preventing incidents through monitoring, maintenance, and risk assessment.
2. Which federal agency regulates hazardous liquid pipelines in the U.S.?
A. EPA
B. PHMSA
C. OSHA
D. DOE
** Verified explanation **
The Pipeline and Hazardous Materials Safety Administration (PHMSA) oversees
pipeline safety standards and regulations.
3. What is a hydrostatic test used to determine?
A. Flow velocity
B. Gas composition
C. Pressure integrity of the pipeline
D. Corrosion rate
** Verified explanation **
Hydrostatic testing checks for leaks and verifies pipeline strength by filling it with
water and applying pressure.
, 4. Which of the following is a common cause of pipeline corrosion?
A. High voltage interference
B. Electrochemical reactions with the environment
C. Pipeline diameter
D. Internal coating failure
** Verified explanation **
Corrosion occurs when metal reacts with its environment, often due to
electrochemical processes.
5. What does the acronym HCA stand for in pipeline integrity management?
A. Hazard Control Assessment
B. High Consequence Area
C. Hydraulic Compression Analysis
D. Hazardous Chemical Area
** Verified explanation **
HCAs are locations where pipeline failure would have significant consequences to
health, safety, or the environment.
6. What is the main function of a cathodic protection system?
A. Prevent pressure surges
B. Detect leaks
C. Prevent corrosion on metal surfaces
D. Strengthen weld joints
** Verified explanation **
Cathodic protection prevents corrosion by applying a small electric current to
counteract natural electrochemical reactions.
7. Which inspection method uses sound waves to detect flaws?
A. Radiographic testing
B. Magnetic particle testing
C. Ultrasonic testing
D. Visual inspection
** Verified explanation **
Ultrasonic testing sends high-frequency sound waves through materials to detect
internal flaws.
8. What is a pipeline "pig"?
