API API-510 問題集

質問 1：
Fillet welded on patches require special design considerations, especially relating to which of the following?
A. Efficiency
B. None of these
C. Shape of the patch
D. Length of previous services of the vessel
正解：A

質問 2：
Risk-based Inspection combines the assessment of?
A. likelihood of failure and the consequence of failure
B. likelihood of failure and the effects on plant operation of failure
C. likelihood of poor inspection and the consequence of failure
D. chances of failure and the cost of failure
正解：A

質問 3：
Under which of the following condition(s) should you require the removal of safety relief device(s)?
A. Blowback had been detected and the manufacturers recommend removal
B. The safety relief device was opening on a irregular, unexplainable basis
C. Surface corrosion on the body of the relief device
D. If a pressure test is being conducted in which the test pressure will exceed the set pressure of the safety relief valve with the lowest setting
正解：D

質問 4：
How does API-510 guide the handling of historical pressure vessels that do not fully comply with current standards?
正解：
API-510 provides guidelines for handling historical pressure vessels that may not fully comply with current standards by offering provisions for grandfathering certain aspects, provided they do not compromise safety. The standard advises on assessing the condition of these vessels through rigorous inspections and determining their fitness for service using current engineering practices. If these vessels can continue to operate safely under their current conditions, they may be allowed to do so with increased monitoring. Otherwise, they must be upgraded or replaced to meet current standards.

質問 5：
A corroded area in a carbon steel vessel is being repaired by using weld overlay (weld build-up).
The vessel surface should be examined by:
A. MT or PT before and after welding
B. MT or PT before welding
C. MT or PT after welding, and UT flaw detection after 24 hours
D. MT or PT after welding
正解：A

質問 6：
Discuss the impact of API-510 on the operational efficiency of pressure vessels and how it helps in optimizing maintenance schedules.
正解：
API-510 significantly impacts the operational efficiency of pressure vessels by establishing standards that help in the early detection of potential issues and scheduling maintenance based on actual vessel condition rather than on fixed intervals. This risk-based inspection (RBI) approach allows for the optimization of maintenance schedules, ensuring that resources are allocated effectively, and downtime is minimized. By implementing these standards, facilities can improve the reliability and availability of their pressure vessels, reduce unexpected failures, and extend the service life of their equipment. API-510's guidelines ensure that maintenance is proactive and aligned with the specific needs of each vessel, based on its operating conditions and history.

質問 7：
The re-rating of a pressure vessel will be considered complete only when the authorized pressure vessel inspector witnesses which of the following?
A. The pressure test required by the code
B. The final painting of the vessel
C. The stamping of welds by each welder
D. The attachment of an additional nameplate of stamping
正解：D

質問 8：
Which API document should be consulted for the repair of pressure relieving devices as per API-510?
A. API 572
B. API 570
C. API 576
D. API 579
正解：C
