質問 # 85
How does API-510 guide the decommissioning process for pressure vessels that are no longer fit for service?
正解：
解説：
API-510 guides the decommissioning process for pressure vessels by outlining a series of steps designed to ensure safety and compliance with environmental regulations. The process begins with a thorough cleaning to remove any hazardous substances, followed by a comprehensive inspection to document the vessel's condition. The vessel is then isolated and, if necessary, cut into manageable sections for removal, using methods that prevent any contamination or environmental impact. Finally, all associated documentation is updated to reflect the decommissioning, and materials are recycled or disposed of in accordance with local environmental standards.
質問 # 86
The surface remote from a welded joint is defined as:
- A. 1 inch on either side of the weld or twice the minimum thickness whichever is less
- B. 1 inch on either side of the weld or twice the minimum thickness whichever is greater
- C. For vessels with inside diameters less than 60 inches 20 inches or ½ the vessel diameter
- D. 2 inches on either side of the weld
正解：B
質問 # 87
When must both an internal and external inspection always be performed?
- A. at installation of vessel
- B. whenever the vessel's ownership changes
- C. whenever there is a change in fluid service
- D. whenever the vessel's ownership and location changes
正解：D
質問 # 88
When a corroded area of considerable size is encountered and the circumferential stresses govern, what is maximum length over which the thickness can be averaged for a vessel with an inside diameter of 48 inches?
- A. 24 inches
- B. 25 percent of the vessel diameter
- C. 20 inches
- D. 20 percent of the vessel diameter
正解：C
質問 # 89
Repairing a crack on a vessel should not be attempted without prior consultation with _________.
- A. Pressure vessel engineer experienced in pressure vessel design
- B. Production manager
- C. The original manufacturer
- D. The company writing the insurance on the vessel
正解：A

- A. When the vessel contains toxic substances
- B. Always prefer pneumatic testing
- C. When water is not available
- D. When the vessel operates under vacuum
正解：A
質問 # 93
What documentation must be reviewed and updated after any major alteration or repair to a pressure vessel as per API-510?
- A. The vessel's operating manual
- B. The latest inspection report
- C. All relevant documentation, including design, operation, and maintenance
- D. The original design documents
正解：C
質問 # 94
Explain the importance of lifecycle assessments in managing pressure vessels under API-510.
正解：
解説：
Lifecycle assessments are crucial in managing pressure vessels under API-510 as they provide a comprehensive evaluation of a vessel's condition throughout its operational life. These assessments help identify potential issues early, allowing for preventative maintenance and repairs that can extend the vessel's life and ensure safety. Lifecycle assessments involve regular inspections, material testing, and performance analyses, which collectively help predict potential failures and plan for decommissioning or upgrades. This proactive approach not only enhances safety and reliability but also optimizes operational costs by preventing unexpected failures and extending the service life of pressure vessels.
