Pressure Vessel Inspection Code: In-Service inspection, Rating, Repair, and Alteration Flashcards
What does the inspection code cover?
The inspection code covers the in-service inspection, repair, alteration, and rerating activities for pressure vessels and the pressure relieving devices protecting these vessels.
What (4) types of vessels does the inspection code cover?
a) Vessels constructed in accordance with an applicable construction code (eg. ASME code)
b) Vessels constructed without a construction code (noncode vessels)
c) Vessels constructed and approved as a jurisdictional special based upon jurisdiction acceptance
d) Nonstandard vessels
What is a non-standard vessel?
A vessel fabricated to a recognized construction code but has lost its nameplate or stamping.
The ASME code and other recognized construction codes are written for _________, however most of the technical requirements for design, welding, NDE, and materials can be applied to the _________, __________, __________, and _________ of ______________
new construction
inspection, rerating, repair, and alteration of in-service vessels.
If in-service vessels are covered by requirements in the construction code and API 510 or if there is a conflict between the two codes, which shall take precedence?
The requirements of API 510
The application of this inspection code is restricted to owner/users that employ or have access to the following technically qualified individuals and organizations:
a) an authorized inspection agency
b) a repair organization
c) an engineer
d) and inspector
e) examiners
For inspection planning and engineering assessment of in-service pressure vessels, this inspection code recognizes the applicability of?
a) Fitness for service (FFS) assessment
b) Risk based inspection (RBI)
Definition: “Alteration”
A physical change in any component that has design implications that affect the pressure containing capability of a pressure vessel beyond the scope described in existing data reports.
What is not considered an “Alteration”?
a) Any comparable or duplicate replacement
b) The addition of any reinforced nozzles less than or equal to the size of existing reinforced nozzles
c) The addition of nozzles not requiring reinforcement
Definition: “Applicable construction code”
Engineering standard or practice to which the pressure vessel was built
Definition: “Authorized inspection agency”
a) the inspection organization of the jurisdiction in which the pressure vessel is used
b) the inspection organization of an insurance company that is licensed or registered to write and does write pressure vessel insurance
c) the inspection organization of an owner or user of pressure vessels who maintains an inspection organization for his/her equipment only and not for vessels intended for sale or resale
d) an independent organization or individual that is under contract to and under the direction of an owner/user and that is recognized or otherwise not prohibited by the jurisdiction in which the pressure vessel is used.
How many examination points for a CML?
one or more
Definition: “Construction code”
The code or standard to which a vessel was originally built
Definition: “Corrosion rate”
The rate of metal loss due to erosion, corrosion, or the chemical reaction with the environment either internal and/or external
Definition: “CUI”
All forms of CUI including stress corrosion cracking and CUF
