NACE CIP2 - (2) Exam Questions and
Answers 100% Pass
Describe air turns - ✔✔eliminates air stratification. 1-2 Turns is sufficient
Below what RH does corrosion virtually cease? - ✔✔40%
2 ways to reduce RH of boundary layer- - ✔✔increase surface temp & dehumidification
2 types of dehumidification equipment: - ✔✔refrigerant & desiccant
Benefits of dehumidification - ✔✔dries air, lowers dew point, holds surface during
coating application, holds blast with dry air, permits blasting the entire surface.
Electronic Hydrometers - ✔✔test RH, air temp, dew point
Basic centrifugal blast set up - ✔✔Tumbling mill, multi table, plain table,swing table,
custom designs
Centrifugal blast with conveyor: - ✔✔plate, rolled shapes, large trusses, grinders
Portable Centrifugal systems - ✔✔ship decks, storage tanks, concrete floors, highways
ans bridges

, Centrifugal systems composed of - ✔✔throwing wheel, enclosure, recycling system,
dust collector and vent pipe, abrasive and material handling (in fixed system)
Blast wheel efficiency depends on - ✔✔mix, size of abrasive, velocity coming off the
wheel, quantity and direction of thrown abrasive & the condition of feed parts
Low Amp reading on centrifugal machine could signify - ✔✔abrasive starved wheel or
flooded/ choked wheel
Centrifugal separator function - ✔✔controls size of abrasive, removed sand/spent
abrasive/rust/dirt, controls abrasive consumption
WJ-1 (visual cleanliness) comparable to: - ✔✔ISO SA3
Waterjetting effectivley removes - ✔✔surface oil and grease, rust , concrete spatter,
existing coating, water soluble contaminants that aren't removed during abrasive blast,
ship hauls or off short platforms
Back thrust - ✔✔1/3 worker weight, causes fatigue
Thermal spray safety - ✔✔Use hoses rated for high pressure, never clean with
compressed air, do not use plant air in breathing apparatus, reduce to less than 30psi for
cleaning
Lining - ✔✔coating usually used in immersion service
Resins used in reinforced linings - ✔✔Polyester Epoxy & vinyl ester
