ASME B31.3 PROCESS PIPING CODE 2026
EXAM COMPLETE (115) CURRENT TESTING
QUESTIONS AND DETAILED CORRECT
ANSWERS|GUARANTEED PASS.
ASME B31.3
Prepare for the ASME B31.3 Process Piping Code Exam with this
concise study resource covering piping design requirements,
materials, fabrication standards, and code compliance. It
reinforces key concepts aligned with standards from the
American Society of Mechanical Engineers. Designed to support
effective preparation and test readiness. Suitable for engineers,
inspectors, and professionals working with process piping
systems.
If a non-toxic flammable liquid is used as a leak testing
medium, it must have: ✓ ✓ ...... ANSWER ....... At least a
flash point of 120 degrees F.
Where the design temperature of the system is the same as
the hydrostatic test temperature, the hydrostatic test
pressure shall not be less than: ✓ ✓ ...... ANSWER .......
1.5 times the design pressure.

What is the formula for calculating hydrostatic test pressure
when the design temperature is above the test temperature?
✓ ✓ ...... ANSWER ....... Min. Test pressure= 1.5 * mop *
stress value at test temperature / stress value at design
temperature
Where the test pressure of piping exceeds the vessels test
pressure, and it is not considered practical to isolate the
piping from a vessel, the piping and the vessel may be tested
together at the vessel test pressure, provided the owner
approves and the vessel test pressure is not less than ___%
of the piping test pressure calculated by ASME B31.3,
paragraph 345.4.2(b). ✓ ✓ ...... ANSWER ....... 77
If a pneumatic leak test is used, the test pressure shall be
___% of the design pressure. ✓ ✓ ...... ANSWER .......
110
If it becomes necessary to use a "sensitive Leak Test"
method, the test pressure shall be at least the lesser of ___
psi or ____% of the design pressure. ✓ ✓ ...... ANSWER
....... 15, 25

Unless otherwise specified by the engineering design, the
following records shall be retained for at least ____ years
after the record is generated for the project: examination
procedures, and examination personnel qualifications. ✓ ✓
...... ANSWER ....... 5
What is the longitudinal weld joint factor, Ej, for API 5L ERW
(electric resistance welded) pipe? ✓ ✓ ...... ANSWER .......
.85 and is found in Table A-1B
What is the casting quality factor, Ec, of a A216 carbon steel
casting that is not upgraded per B31.3 paragraph 302.3.3(c)
and table 302.3.3C ✓ ✓ ...... ANSWER ....... .80 and is
found in Table A-1A
You have carbon steel pipe that has <= .3% carbon in it. what
is its Modulus of Elasticity at 400 degrees F.? ✓ ✓ ......
ANSWER ....... 27,700,000 and is found Table C-6
Double welded slip-on flanges should be ____ between the
welds for fluid services that require leak testing of the inner
fillet weld , or when fluid handled can diffuse into the
