出題：7

Explain the process of integrating new materials technology in the construction of pressure vessels as per API-510.

正解：

Integrating new materials technology in the construction of pressure vessels as per API-510 involves thorough testing and evaluation to ensure compatibility with existing standards. This includes mechanical and chemical property testing, long-term durability assessments, and compatibility checks with the contents to be stored or processed in the vessels. API-510 requires that all new materials be approved based on their ability to maintain structural integrity under the operating conditions specified for the vessel. The use of new materials must also be documented in detailed engineering reports and reviewed by certified inspectors.

Under API-510, when is a pressure vessel subject to mandatory stress relieving?

A. After any repair

B. After alterations that involve cutting or welding on critical areas

C. After every major repair

D. When the thickness of the vessel is reduced by 10%

正解：B 解答を投票する
