According to API 1104, what must be done if a defect is found during inspection?

The requirement in API 1104 to repair and re-inspect a defect found during inspection is grounded in the importance of maintaining the integrity and safety of pipelines and related facilities. When a defect is identified, whether it is a flaw in the weld or an issue with the material, it poses a potential risk to the overall system.

The process of repairing the defect ensures that the quality and performance standards established by the code are met, thereby reducing the likelihood of failures that could lead to leaks, environmental issues, or hazardous conditions. After the repair is completed, re-inspection serves as a critical step to verify that the repair was successful and that the weld now complies with the necessary specifications. This thorough approach aligns with the overarching goal of ensuring pipeline safety and reliability.

In contrast, simply documenting and ignoring a defect would compromise safety and potentially lead to serious consequences down the line. Marking a defect for future reference does not address the underlying problem and could result in the defect being overlooked in future inspections. Reporting the defect to management could be a necessary step, but without taking action to repair and re-inspect, the defect remains unresolved and poses a threat. Therefore, the requirement for repair and re-inspection is a proactive measure that safeguards the integrity of
