Are bare spots on a joint or fitting considered a serious defect?

Bare spots on a joint or fitting are considered a serious defect because they can indicate a failure in the protective coating or finish that is essential for preventing corrosion and deterioration of the underlying material. These defects compromise the integrity of the joint or fitting, potentially leading to leaks and failures, especially in systems that experience movement, pressure changes, or exposure to corrosive environments.

In high-pressure applications, the risks associated with bare spots are amplified, but the issue is significant across all applications. Whether the bare spots are in visible areas or not does not change the fact that they can jeopardize the overall reliability and longevity of the piping system. Therefore, identifying and addressing these defects is crucial to maintaining safety and performance standards in pipe fitting.
