In which areas should lines that sweat or have moisture be inspected for external corrosion?

• A. At the connections only
• B. Under clamps and at rollers
• C. At the flange joints
• D. Along the entire length of the pipe

Answer: (B)

The most effective approach for inspecting lines that sweat or have moisture is to focus on specific areas that are prone to external corrosion. Inspecting under clamps and at rollers is crucial because these locations often trap moisture and debris, creating an environment conducive to corrosion. Clamps can restrict airflow and moisture evaporation, leading to localized corrosion underneath where the clamp is applied. Similarly, rollers can accumulate water or become a point of contact that promotes wear and corrosion of the underlying pipe. While it is important to inspect all potential corrosion spots, choosing the right inspection areas increases the likelihood of detecting and mitigating corrosion issues before they lead to significant damage. Thus, the focus on clamps and rollers addresses real, high-risk areas in piping systems where moisture could lead to corrosion.
