questions and correct detailed answers
Quiz 3.1.1 Abandoned-In-Place
Ans: Piping system, circuit or contiguous sections thereof meeting all of the
following: has been decommissioned with no intention for future use; has been
completely de-inventoried/purged of hydrocarbon/chemicals; and is physically
disconnected (e.g. air-gapped) from all energy sources and/or other
piping/equipment.
Quiz 3.1.2 Alloy Material
Ans: Any metallic material (including welding filler materials) that contains alloying
elements, such as chromium, nickel, or molybdenum, which are intentionally added
to enhance mechanical or physical properties and/or corrosion resistance. Alloys
may be ferrous or non-ferrous based. NOTE: Carbon steels are not considered
alloys, for purposes of this Code.
Quiz 3.1.3 Alteration
Ans: A physical change in any component that has design implications affecting the
pressure containing capability or flexibility of a piping system beyond the scope of its
original design. The following are not considered alterations: comparable or duplicate
replacements and replacements in kind.
Quiz 3.1.4 Applicable Code
Ans: The code, code section, or other recognized and generally accepted
engineering standard or practice to which the piping system was built or which is
deemed by the owner/user or the piping engineer to be most appropriate for the
situation, including but not limited to the latest edition of ASME B31.3.
Quiz 3.1.5 Authorization
,Ans: Approval/agreement to perform a specific activity (e.g. piping repair) prior to the
activity being performed.
Quiz 3.1.6 Authorized Inspection Agency
Ans: Defined as any of the following:
a) the inspection organization of the jurisdiction in which the piping system is used,
b) the inspection organization of an insurance company that is licensed or registered
to write insurance for piping systems;
c) an owner or user of piping systems who maintains an inspection organization for
activities relating only to his equipment and not for piping systems intended for sale
or resale;
d) an independent inspection organization employed by or under contract to the
owner/user of piping systems that are used only by the owner/user and not for sale
or resale;
e) an independent inspection organization licensed or recognized by the jurisdiction
in which the piping system is used and employed by or under contract to the
owner/user.
Quiz 3.1.7 Authorized Piping Inspector
Ans: An employee of an owner/user organization or authorized inspection agency
(3.1.6) who is qualified and certified by examination under the provisions of Section 4
and Annex A and is able to perform the functions specified in API 570 where
contracted or directed to do so. An NDE examiner is not required to be an authorized
piping inspector. Whenever the term inspector is used in API 570, it refers to an
authorized piping inspector.
Quiz 3.1.8 Auxiliary Piping
Ans: Instrument and machinery piping, typically small-bore secondary process
piping that can be isolated from primary piping systems but is normally not isolated.
Examples include flush lines, seal oil lines, analyzer lines, balance lines, buffer gas
lines, drains, and vents.
Quiz 3.1.9 Condition Monitoring Locations CMLs
Ans: Designated areas on piping systems where periodic examinations are
conducted in order to assess the condition of the piping. CMLs may contain one or
more examination points and utilize multiple inspection techniques that are based on
the predicted damage mechanism(s). CMLs can be a single small area on a piping
system e.g. a 2 in. diameter spot or plane through a section of a pipe where
examination points exist in all four quadrants of the plane. NOTE: CMLs now include,
but are not limited to what were previously called TMLs.
Quiz 3.1.10 Construction Code
Ans: The code or standard to which the piping system was originally built (e.g.
ASME B31.3).
, Quiz 3.1.11 Contact Point
Ans: The locations at which a pipe or component rests on or against a support or
other object which may increase its susceptibility to external corrosion, fretting, wear
or deformation especially as a result of moisture and/or solids collecting at the
interface of the pipe and supporting member.
Quiz 3.1.12 Corrosion Allowance
Ans: Material thickness in excess of the minimum required thickness to allow for
metal loss (e.g. corrosion or erosion) during the service life of the piping component.
NOTE: Corrosion allowance is not used in design strength calculations.
Quiz 3.1.13 Corrosion Barrier
Ans: The corrosion allowance in FRP equipment typically composed of an inner
surface and an interior layer which is specified as necessary to provide the best
overall resistance to chemical attack.
Quiz 3.1.14 Corrosion Rate
Ans: The rate of metal loss (e.g. reduction in thickness due to erosion,
erosion/corrosion or the chemical reaction(s) with the environment, etc.) from internal
and/or external damage mechanisms.
Quiz 3.1.15 Corrosion Specialist
Ans: A person acceptable to the owner/user who is knowledgeable and experienced
in the specific process chemistries, degradation mechanisms, materials selection,
corrosion mitigation methods, corrosion monitoring techniques, and their impact on
piping systems.
Quiz 3.1.16 Corrosion Under Insulation (CUI)
Ans: External corrosion of carbon steel and low alloy steel piping resulting from
water trapped under insulation. External chloride stress corrosion cracking (ECSCC)
of austenitic and duplex stainless steel under insulation is also classified as CUI
damage.
Quiz 3.1.17 Critical Check Valves
Ans: Check valves in piping systems that have been identified as vital to process
safety (see 5.13). Critical check valves are those that need to operate reliably in
order to avoid the potential for hazardous events or substantial consequences
should reverse flow occur.
Quiz 3.1.18 Cyclic Service
