API 510 Practice Test (Referenced) Questions With
Complete Solutions
A crack in a vessel at the cone-to-cylinder juncture can be
repaired with approval by the API-authorized inspector provided
that:
API 510 8.1.2 Correct Answers An engineer has also
authorized the work.
A plant engineer would like to increase a vessel's operating
temperature by 100˚F. The vessel's nameplate states a maximum
allowable working pressure of 250 psig at 650˚F, and the current
operating temperature is 600˚F. What is the first step in
increasing the operating temperature?
API 510 8.2.1 a/c Correct Answers Perform calculations to
determine if the vessel thickness is sufficient.
A pneumatic testing precedure should be developed by whom
before conducting the test?
API 510 5.8.6 Correct Answers Engineer
A pressure vessel has been in non-continuous service for 15
years. During this time, it has been filled three times for 2 years
at a time, then internally inspected. The last internal inspection
determined that the vessel had 9 years remaining life. The next
inspection is due:
API 510 6.5.1.1 Correct Answers Before 4.5 years of actual
service.
A signal of discontinuity in the material under nondestructive
examination is considered:
, API RP 577 3.1.36 Correct Answers Indication
A vessel has a single corrosion rate of 10 mils per year. The
minimum vessel required thickness for both the shell and the
heads is 0.75 inch. The actual thickness of the heads is 0.95 inch
and the shell is 0.90 inch. What is the vessel's remaining life?
API 510 7.2.1 Correct Answers 15 yrs
A welding technique where the heat and placement of weld
passes in deposited weld layers is controlled so that sufficient
heat is provided to temper each previously deposited weld layer
is known as:
API 577 3.1.65 Correct Answers Temper Bead Welding.
Above what pressure is a vessel considered to be in the scope of
the API Code?
API 510 Annex A (b) (8) Correct Answers 15 psig
ACFM is an acronym for:
ASME SEC 5 Article 15 Correct Answers Alternating Current
Field Measurement
After an alteration to a pressure vessel, a nondestructive
examination (NDE) procedure may be substituted for a pressure
test only when:
API 510 5.8.8.1 Correct Answers The engineer and inspector
have approved.
An example of vessels not covered by API 510 are:
API 510 1.1.1 Correct Answers Vessels officially retired from
service and abandoned in place.
