NACE CIP Level 2 Questions With Answers
100% Correct
What does waterjetting not create? 7-1 An anchor profile
In the marine industry, waterjetting is widely used for what purposes? 7-1 Removal of
marine growth, depleted antifouling coatings and surface preparation of tank/hold interiors
What industries is waterjetting particularly well suited for? 7-1 Marine, process and utility
industries.
What standard specifies the amount of non visible contaminants that are allowed to be left on the
surface? 7-5 None. If the coating specification does not require testing, the inspector
should not request the contractor to do so or do so on his own accord.
What parts does a commercial waterjet unit consist of? 7-6 pumps, hoses, prime mover,
and various tools such as guns, nozzles and lances
What should the minimum burst strength of high-pressure equipment be? 7-7 2 1/2 times
the capability of its maximum-rated operating strength.

What is the effect when waterjetting at pressures lower that 10,000psig? loose rust, debris,
and material in depressions and pits are removed but magnetite remains. A matte finish is not
achieved.
Describe what robotic waterjetting is. 7-8 It is a cleaning vehicle that attaches itself, using
