NACE CIP Level 2 Questions & Answers
SSPC PA9
Correct Answer:
Measure of DFT on cement substrates
ASTM D6132-97
Correct Answer:
NON DESTRUCTIVE measurement of dry film thickness of applied organic coating to
CONCRETE using ULTRASONIC gauge
Low voltage Holiday detector procedure
Correct Answer:
Ground cable to substrate, saturate sponge with tap water & wetting agent, max rate
1ft/sec double stroke, used on coating up to 20 mils
(may be used on concrete)

Mainline plant applied coatings:
Correct Answer:
2 layer PE, 3 layer PE, FBE, Tapes, Coal tar enamel, Asphalt, Insulated, Concrete
PE= Polyethylene
Polyethylene (PE) extruded by
Correct Answer:
Side extrusion for large diameter pipe and crosshead extrusion
FBE Characteristics (Fusion Bonded Epoxy)
Correct Answer:
Green or red
looks like painted finish
single layer or dual power (2 layer)
DFT 10-20mils
FBE application process
Correct Answer:
Pre heat pipe, grit or shot blast to Nace 2/ SSPC SP 10, optional acid bath, heat pipe to
specified temp, apply FBE coating, cure, fresh water bath, stencil.

Advantages of Coat Tar Enamel
Correct Answer:
Ease of application & long life in some environments
Disadvantages of Coat Tar Enamel
Correct Answer:
Corrosion and damage from soil stress, environmental and exposure concerns, use of
coal is regulated in some locations.
Application process for Coal Tar Enamel (CTE)
Correct Answer:
Prime the pipe, apply CTE dope, wrap with glass fiber mat, apply more CTE dope, 2nd
layer of glass mat, apply outer wrap of coal tar impregnated glass fiber felt, cool the
application.
Concrete coating characteristics:
Correct Answer:
Used in conjunction with other coating (ie FBE), reduces buoyancy so pipe will sink,
applied in many thicknesses, can be applied to any diameter of pipe
