質問 2：
Discuss the implications of deferred maintenance on pressure vessels and how API-510 helps to mitigate these risks.
正解：
Deferred maintenance on pressure vessels can lead to serious safety risks, including the potential for catastrophic failures. API-510 mitigates these risks by setting strict guidelines for inspection and maintenance schedules based on the condition and service history of the vessels. The standard emphasizes the importance of adhering to these schedules and provides criteria for risk-based inspections that prioritize maintenance tasks based on the urgency and potential impact of defects. This proactive approach helps prevent the deterioration of vessel condition and ensures that maintenance is performed before any serious issues arise.

A. The corners shall be rounded 1 inch minimum radius
B. The corners shall be provided with a 6 inch radius
C. The corners shall be provided with a 3 inch radius
D. The corners shall be squared
正解：A

質問 4：
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 after welding, and UT flaw detection after 24 hours
B. MT or PT before and after welding
C. MT or PT after welding
D. MT or PT before welding
正解：B

質問 5：
Explain how API-510 facilitates the upgrade of older pressure vessels to meet modern safety and efficiency standards.
正解：
API-510 facilitates the upgrade of older pressure vessels to meet modern safety and efficiency standards by providing guidelines for assessing their current condition and determining the feasibility of various upgrade options. This includes evaluating the compatibility of new materials and technologies with the existing vessel structure and determining the necessary modifications to enhance performance and safety. API-510 also outlines the required inspections and tests to certify that upgraded vessels comply with current standards, ensuring that they can continue to operate safely and efficiently.

質問 6：
Discuss the impact of API-510 on global industry practices for the maintenance and inspection of pressure vessels.
正解：
API-510 has a significant impact on global industry practices for the maintenance and inspection of pressure vessels by setting internationally recognized standards that ensure safety, reliability, and compliance. These standards influence how companies around the world develop their maintenance and inspection programs, promoting a consistent and high level of practice across industries. API-510 has led to improved safety records, extended equipment life, and reduced incidence of vessel failures. Moreover, the standard fosters innovation in inspection techniques and maintenance strategies, contributing to ongoing improvements in the field.
