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 one for purposes of this code.
Right Ans - alloy material
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 the addition of small-bore
attachments that do not require reinforcement
or additional support. Right Ans - Alteration
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 or user or the
piping engineer to be most appropriate for the
situation, including but not limited to the latest edition of ASME B31.3.
Right Ans - applicable code
Approval/agreement to perform a specific activity (e.g. repair) prior to the
activity being performed. Right Ans - Authorization
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 or user of piping systems that are used only by the owner or 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 or user. Right Ans - Authorized Inspection Agency
An employee of an authorized inspection agency who is qualified and certified
to perform the functions specified in API 570. 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. Right Ans -
authorized piping inspector
Instrument and machinery piping, typically small-bore secondary process
piping that can be isolated from primary piping systems. Examples include
flush lines, seal oil lines, analyzer lines, balance lines, buffer gas lines, drains,
and vents. Right Ans - auxiliary piping
Designated areas on piping systems where periodic examinations are
conducted. NOTE Previously, CMLs were referred to as "thickness monitoring
locations" (TMLs). CMLs may contain one or more examination points. CMLs
can be a plane through a section of piping or a nozzle or an area where CMLs
are located on a piping circuit. Right Ans - CMLs
The code or standard to which the piping system was originally built (i.e.
ASME B31.3). Right Ans - construction code
Check valves in piping systems that have been identified as vital to process
safety. Right Ans - critical check valves
Any type of deterioration encountered in the refining and chemical process
industry that can result in flaws/defects that can affect the integrity of piping
(e.g. corrosion, cracking, erosion, dents, and other mechanical, physical or
chemical impacts). Right Ans - damage mechanism
Components of a piping system that normally have no significant flow. Some
examples include blanked branches, lines with normally closed block valves,
lines with one end blanked, pressurized dummy support legs, stagnant control
valve bypass piping, spare pump piping, level bridles, relief valve inlet and
