Pipeline Corrosion Integrity Management (PCIM)
Technician Certification Exam
1. The primary purpose of Pipeline Corrosion Integrity
Management is:
A. Relocate pipelines away from cities
B. Prevent, detect, and mitigate corrosion-related
failures
C. Reduce pipeline diameter for cost efficiency
D. Increase pipeline operating pressure
Answer: B
Explanation: PCIM focuses on reducing risk by
identifying corrosion threats, monitoring, and applying
preventive actions.
2. Which type of corrosion occurs when a metal is
exposed to moisture and oxygen?
A. Galvanic corrosion
B. Atmospheric corrosion
C. Pitting
D. Microbiologically influenced corrosion
Answer: B
Explanation: Atmospheric corrosion results from
,exposure to air and humidity, common in above-
ground pipelines.
3. Which pipeline coating type is most commonly used
for buried steel pipelines?
A. Zinc plating
B. Polyethylene or fusion-bonded epoxy
C. Galvanized paint
D. Copper cladding
Answer: B
Explanation: FBE and PE coatings provide long-term
corrosion resistance for underground pipelines.
4. Cathodic protection works by:
A. Electrically making steel the cathode of an
electrochemical cell
B. Painting pipelines with metal flakes
C. Increasing soil resistivity
D. Heating the pipeline
Answer: A
Explanation: CP prevents corrosion by forcing corrosion
reactions away from pipeline steel.
,5. Impressed current cathodic protection uses which of
the following?
A. Natural galvanic reaction only
B. DC power source and anodes
C. Only sacrificial magnesium anodes
D. AC power with graphite coating
Answer: B
Explanation: ICCP systems use rectifiers and anodes to
control protective current.
6. A pipeline integrity assessment is carried out to:
A. Increase pipeline diameter
B. Lower fuel consumption
C. Evaluate condition and identify threats
D. Monitor customer billing
Answer: C
Explanation: Integrity assessments detect anomalies
like corrosion, metal loss, and defects.
7. Which inspection tool is used to detect corrosion
metal loss internally?
A. Pig brush
B. Magnetic flux leakage (MFL) tool
, C. Gas leak detector
D. Fiber optic camera only
Answer: B
Explanation: MFL pigs detect metal thickness loss
through magnetic field disturbance.
8. The maximum allowable operating pressure (MAOP)
is set based on:
A. Customer usage
B. Pipe material strength and integrity condition
C. Daily weather
D. Pump manufacturer preference
Answer: B
Explanation: MAOP must align with pipe grade, test
records, and safety margins.
9. Soil with low resistivity increases corrosion risk
because:
A. It becomes a high insulator
B. It holds moisture and allows ion flow
C. It blocks electrochemical reactions
D. Prevents bacteria growth
