Under what circumstance should drilling test holes be deployed on piping systems?

• A. When visual inspections show corrosion
• B. When UT or RT services are unavailable
• C. When the system is fully operational
• D. When doing routine maintenance

Answer: (B)

Drilling test holes is typically employed when there are limitations in available inspection technologies, such as when ultrasonic testing (UT) or radiographic testing (RT) services cannot be performed. These testing methods provide comprehensive insights into the internal conditions of pipes, and when they are unavailable, drilling test holes becomes a practical alternative to assess the condition of the piping system. This method allows for a direct examination of the material condition, especially in areas where corrosion or other degradation may not be visually detectable. It provides valuable information that can inform decisions regarding repairs or replacements within the system. In situations where advanced methodologies are not available, this approach ensures that critical assessments can still be executed effectively.
