What is the maximum diameter for an examination point?

• A. 1"
• B. 2"
• C. 3"
• D. 6"

Answer: (C)

The maximum diameter for an examination point is 3 inches. This specification is important in ensuring that the examinations conducted on pressure vessels are thorough and accurate without compromising the integrity of the vessel or the safety of personnel. Examination points are typically defined as small openings that allow for inspection of welds, corrosion, or other potential issues within a pressure vessel. A diameter of 3 inches allows sufficient access for the inspector to visualize, assess, and perform necessary measurements or tests while maintaining the structural integrity of the pressure vessel. Using diameters larger than 3 inches could introduce complications, such as increased risks of compromising the vessel's integrity or encountering difficulties in obtaining accurate inspection data. Therefore, adhering to the maximum allowable diameter helps maintain safety standards and complies with inspection protocols outlined in relevant codes and standards.
