ASME B31.3 PROCESS PIPING EXAMINATION
TEST 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◉ Clauses in the B31 code are not necessarily numbered consecutively.
Such discontinuities result from: Answer: Following a common outline,
insofar as practical for all code sections.
◉ Who has the responsibility of determining which code section is
applicable to piping installations, i.e., B31.1, B31.3 etc? Answer: Owner
◉ Who has the overall responsibility for compliance with ASME B31.3?
Answer: Owner
◉ The intent of ASME B31.3 is to set forth engineering requirements
deemed necessary for ________. Answer: Safe design and construction
of piping installations.
◉ ASME Code is not intended to apply to piping: Answer: That has
been placed in service.
,◉ Compatibility of materials with the service and hazards from
instability of contained fluids: Answer: Are not within the scope of
ASME B31.3.
◉ ASME B31.3 applies to piping for all fluids except for: Answer:
Tubes of fired heaters, plumbing, and storm sewers.
◉ A prep laced filler metal which is completely fused into the root of a
welded joint and becomes part of the weld is called: Answer: A
consumable insert.
◉ Define "face of weld". Answer: It is the exposed surface of a weld on
the side from which the welding was done.
◉ A fluid service that is non-flammable, nontoxic, and not damaging to
human tissue and it's gage pressure does not exceed 150 psi and the
design temperature is from -20 degrees through 366 degrees F is known
as a category _____ fluid. Answer: D
◉ A fluid service which has the potential for personnel exposure is
judged to be significant and in which a single exposure to a very small
quantity of a toxic fluid, caused by leakage, can produce serious
irreversible harm to persons on breathing or bodily contact, even when
prompt restorative measures are taken is known as a category ______
fluid. Answer: M
, ◉ A fillet weld whose size is equal to the thickness of the thinner
member joined is called: Answer: A full fillet weld.
◉ The heating of metal to and holding at a suitable temperature and then
cooled at a suitable rate for such purposes as: reducing hardness,
improving machinability, facilitating cold working, producing a desired
microstructure, or obtaining desired mechanical, physical, or other
properties is known as: Answer: Annealing
◉ A piping joint that for the purpose of mechanical strength is
developed by threaded, grooved, rolled, flared, or flanged pipe ends, or
by bolts, pins, toggles or rings; and the leak resistance is developed by
threads and compounds, gaskets, rolled ends, caulking, or machined and
mated surfaces is known as a: Answer: Mechanical joint
◉ The term NPS 6 refers to: Answer: A pipe whose outside diameter is
6.625"
◉ A pipe produced by piercing a billet followed by rolling or drawing,
or both is a: Answer: Seamless pipe
◉ What is a root opening? Answer: It is the separation between
members to be joined by welding, at the root of the joint.
