1. The primary objective of pipeline integrity management is to:
A. Increase pipeline throughput
B. Reduce operating costs
C. Prevent failures and protect people, property, and the
environment
D. Extend pipeline length
Pipeline integrity programs focus on identifying, assessing, and mitigating
risks to prevent leaks, ruptures, and associated hazards.
2. Which mechanism is the most common cause of external corrosion on
buried pipelines?
A. High internal pressure
, B. Poor welding technique
C. Inadequate coating and cathodic protection
D. Improper pigging
External corrosion typically results from coating damage combined with
insufficient cathodic protection.
3. Cathodic protection works by:
A. Increasing pipe wall thickness
B. Making the pipeline the cathode of an electrochemical cell
C. Drying surrounding soil
D. Raising pipeline temperature
Cathodic protection reduces corrosion by forcing the pipeline to act as a
cathode, preventing metal loss.
4. Which inspection method is best for detecting metal loss due to
corrosion?
A. Ultrasonic crack detection
B. Magnetic flux leakage (MFL)
C. Hydrostatic testing
D. Radiographic weld testing
,MFL tools are designed to detect changes in magnetic fields caused by
corrosion-related wall loss.
5. A hydrostatic pressure test is primarily used to:
A. Detect coating defects
B. Measure flow efficiency
C. Verify pipeline strength and integrity
D. Inspect valves
Hydrostatic testing confirms the pipeline can safely withstand operating
pressures without failure.
6. Which regulation governs gas pipeline integrity management in the
United States?
A. OSHA 29 CFR 1910
B. 49 CFR Part 192
C. ASME B31.1
D. API RP 1160
49 CFR Part 192 establishes federal safety standards for gas pipeline
systems.
, 7. Stress corrosion cracking (SCC) is most often associated with:
A. High flow velocity
B. Internal corrosion
C. Tensile stress and corrosive environments
D. Manufacturing defects only
SCC occurs when tensile stress combines with specific environmental
conditions, leading to cracking.
8. Which pig type is used primarily for cleaning pipelines?
A. Intelligent pig
B. Geometry pig
C. Utility (cleaning) pig
D. Caliper pig
Utility pigs remove debris, wax, and liquids to maintain pipeline efficiency.
9. What is a High Consequence Area (HCA)?
A. Area with high pipeline pressure
