What is the main consequence of corrosion on pipelines?

Corrosion on pipelines primarily leads to an increased risk of leaks. When metal pipes corrode, the structural integrity of the material is compromised, creating weak spots. As corrosion progresses, holes or cracks can form, allowing fluids to escape and potentially cause environmental damage or service disruption. This deterioration not only creates safety hazards but also can result in costly repairs and maintenance challenges for the pipeline system.

In contrast, the other options do not accurately reflect the effects of corrosion. Improved heat transfer, reduction in weight, and enhanced flow capacity are not outcomes associated with corrosion; rather, they may be unwarranted assumptions or misinterpretations of how pipelines function efficiently. When corrosion is present, it typically hinders the flow capacity and does not enhance any of the thermal or hydraulic characteristics of the pipeline systems. Thus, recognizing the critical relationship between corrosion and the risk of leaks is essential for effective pipeline management and maintenance.
