What are pipeline leaks?
Unlike other pipeline defects, a leak represents a failure of the pipeline system, even if the damage appears minor. A pipeline leak occurs when a defect completely penetrates the pipe wall, allowing the transported medium to escape.1,2
How do leaks occur?
Leaks can develop from progressive defect growth, which means small imperfections that worsen over time due to corrosion, fatigue, or mechanical stress. They can also be caused by external influences or structural weakness.1
Why are pipeline leaks a risk for pipeline safety?
A pipeline fundamentally fails once a leak forms, regardless of whether a major spill occurs. Pipeline leaks pose significant risks because they compromise containment, leading to environmental pollution and safety hazards. If not addressed promptly, even small leaks can escalate into catastrophic failures. Leaks often indicate underlying structural issues that require urgent investigation and repair. Therefore, preventing leaks is essential for maintaining pipeline safety, protecting the environment, and ensuring operational reliability.1
