REAL EXAM
Describe what the characteristics of a heavy flash rusted surface
are. 7-5 ......-ANSWER--.....Rust that is loosely adherent, easily
comes of, & leaves significant marks on a cloth that is lightly wiped
over the surface.
Describe what the characteristics of a moderate flash rusted surface
are. 7-5 ......-ANSWER--.....Rust that is reasonably well adherent
and leaves light marks on a cloth that is lightly wiped over the
surface.
Describe what the characteristics of a light flash rusted surface are.
7-5 ......-ANSWER--.....Rust that is tightly adherent & not easily
removed by lightly wiping with a cloth.
At what psig is low-pressure cleaning preformed at? 7-2
,2|Page
......-ANSWER--.....below 5000 psig
At what psig is high-pressure cleaning preformed at? 7-2
......-ANSWER--.....5000-10,000 psig
At what psig is high-pressure waterjetting preformed at? 7-2
......-ANSWER--.....10,000-30,000 psig
At what psig is ultrahigh-pressure waterjetting preformed at 7-2
......-ANSWER--.....above 30,000 psig
What does waterjetting not create? 7-1 ......-ANSWER--.....An
anchor profile
In the marine industry, waterjetting is widely used for what
purposes? 7-1 ......-ANSWER--.....Removal of marine growth,
depleted antifouling coatings and surface preparation of tank/hold
,3|Page
interiors What industries is waterjetting particularly well suited
for? 7-1 ......-ANSWER--.....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 ......-ANSWER--
.....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 ......-
ANSWER--.....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 ......-ANSWER--.....2 1/2 times the capability of
its maximum-rated operating strength.
What is the safety device that high-pressure hoses are fitted with?
, 4|Page
7-7 ......-ANSWER--.....whip-lock or whip check
What is the section of hose next to the gun fitted with? 7-7
......-ANSWER--.....hose shroud
What are the two basic categories that waterjetting equipment fall
into? 7-7 ......-ANSWER--.....Manual & Robotic
What category does the majority of waterjetting fall into? 7-8
......-ANSWER--.....manual
What is the effect when waterjetting at pressures lower that
10,000psig? ......-ANSWER--.....loose rust, debris, and material in
depressions and pits are removed but magnetite remains. A matte
finish is not achieved.
