"Tell-tale" or "Sentinel" holes are also known as what?

• A. Delforez holes
• B. Inspection holes
• C. Access ports
• D. Corrosion monitoring points

Answer: (A)

The correct answer is "Delforez holes." These terms refer specifically to small openings that are created in piping systems to act as indicators for moisture or corrosion, allowing operators to monitor the condition of the pipes without requiring extensive disassembly or shutdown of the system. The concept of tell-tale or sentinel holes is have them serve as a proactive measure to detect corrosion at an early stage, thus preventing potential leaks or failures. Choosing the term "Inspection holes" doesn't accurately reflect the specific purpose these holes serve, which is more about monitoring rather than general inspection access. "Access ports" refers to larger openings that provide access for maintenance or inspection but are not necessarily targeted for monitoring corrosion. "Corrosion monitoring points" is a related concept but does not specifically use the terminology commonly associated with this particular term. Therefore, "Delforez holes" is the term that best describes this type of monitoring approach in piping systems.
