A pipeline is transporting natural gas at high pressure, and a technician must ensure safe operation;
which factor is most critical to monitor continuously?
A. Pipe color
B. Pressure levels within allowable limits
C. Pipe length only
D. Ambient lighting conditions
Answer: B
Rationale: Maintaining pressure within design limits is essential for preventing leaks or failures.
2.
A pipeline installer is selecting materials for a high-pressure system; what property is most important?
A. Pipe color
B. Pressure rating and material strength
C. Pipe shape
D. Installation time
Answer: B
Rationale: Materials must withstand operational pressure without failure.

3.
During trenching for pipeline installation, what is the primary purpose of proper bedding?
A. Increase pipeline pressure
B. Provide uniform support and prevent pipe damage
C. Reduce pipe length
D. Improve flow rate
Answer: B
Rationale: Bedding distributes load evenly and protects the pipe from stress.
4.
What is the primary purpose of hydrostatic testing in pipelines?
A. Increase flow rate
B. Verify pipeline integrity under pressure using water
C. Reduce corrosion
D. Improve insulation
, Page 4 of 139
Answer: B
Rationale: Hydrostatic testing identifies leaks and structural weaknesses.
5.
A technician observes corrosion on a steel pipeline; what is the most common protective method used?
A. Painting only
B. Cathodic protection
C. Increasing flow rate
D. Adding insulation
Answer: B
Rationale: Cathodic protection prevents electrochemical corrosion.
6.
Which valve type is commonly used for fully open or fully closed pipeline control?
A. Globe valve
B. Gate valve
