What should be done if internal visual inspection of a pipe reveals erratic corrosion or erosion?

• A. Report the findings and wait for further instructions
• B. Replace the entire section of pipe
• C. Thickness gage the inaccessible areas using UT or RT
• D. Seal the affected areas

Answer: (C)

When conducting an internal visual inspection and encountering signs of erratic corrosion or erosion, it's crucial to assess the extent and severity of the material loss. The correct approach involves utilizing thickness gauging methods, such as ultrasonic testing (UT) or radiographic testing (RT), to obtain precise measurements of wall thickness in areas that may not be visually accessible. This data helps determine whether the integrity of the pipe is compromised and guides subsequent actions. Assessing the thickness provides valuable insight into the condition of the pipe, allowing for informed decision-making regarding repairs or replacements. This method ensures that any hidden corrosion or erosion can be identified and quantified, which is essential for maintaining system integrity and reliability. Visual inspections alone may not provide a complete picture, hence the need for these advanced measurement techniques. In contrast, simply reporting the findings and waiting for further instructions does not address the immediate need for a thorough evaluation of the pipe's integrity. Replacing an entire section of pipe could be unnecessarily drastic without concrete evidence of critical failure. Sealing affected areas may only be a short-term solution and does not resolve the underlying issues of corrosion or erosion, potentially leading to further problems down the line. Thus, measuring wall thickness with UT or RT is the most appropriate and effective course of action
