ASME B31.3 TEST PAPER QUESTIONS AND
SOLUTIONS 2026 GRADED A+
◉ ASME Code section B31.1 retroactivity. Answer: Are retroactive and
all piping installed per earlier additions must be upgraded.
◉ ASME Code section B31.1 non-retroactivity. Answer: Are not
retroactive and all piping installed per earlier editions need not to be
upgraded.
◉ Code section applicability responsibility. Answer: Owner, Inspector,
Jurisdiction, Engineer.
◉ Overall responsibility for compliance. Answer: Owner, Inspector,
Jurisdiction, Engineer.
◉ Intent of ASME B31.3. Answer: To set forth engineering requirements
deemed necessary for Safe Design and construction.
◉ AMSE code application limitation. Answer: AMSE code is not
intended to apply to piping in the chemical industry, that has been in
service, in the agronomy industry, or in the space industry.
,◉ Material compatibility coverage. Answer: Is covered extensively by
ASME B31.3.
◉ Fluid services excluded by ASME B31.3. Answer: Tubes of fired
heaters, plumbing, and storm sewers.
◉ Consumable insert definition. Answer: A preplaced filler metal which
is completely fused into the root of a welded joint and becomes part of
the weld.
◉ Face of weld definition. Answer: It is the exposed surface of a weld
on the side from which the welding has been done.
◉ Category D fluid definition. Answer: A fluid service that is
nonflammable, nontoxic and not damaging to human tissue and its gauge
pressure does not exceed 150 psi and the design pressure is from -20F
through 366 F.
◉ Category H fluid definition. Answer: A fluid service in which 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 can produce
serious irrevocable harm.
, ◉ Full fillet weld definition. Answer: A fillet weld whose size is equal to
the thickness of the thinner member joined.
◉ Annealing definition. Answer: The heating of metal and holding at a
suitable temperature and then cooling at a suitable rate for purposes such
as reducing hardness, improving machinability, or obtaining desired
properties.
◉ Mechanical joint definition. Answer: A piping joint that develops
mechanical strength by threaded, grooved, rolled, flared or flanged pipe
ends.
◉ NPS 6 definition. Answer: A pipe whose outside diameter is 6.625".
◉ Seamless pipe definition. Answer: A pipe produced by piercing a
billet followed by rolling or drawing, or both.
◉ Root opening definition. Answer: It is the separation between
members to be joined by welding, at the root of the joint.
◉ Seal Weld definition. Answer: A weld intended primarily to provide
joint tightness against leakage in metallic piping.
◉ Tack Weld definition. Answer: A weld made to hold parts of a
weldment in proper alignment until the final welds are made.
