Introduction to Pipeline Integrity
•
•
Pipelines transport oil, gas, and chemicals across vast distances efficiently.
Pipelines are critical for energy security and industrial operations worldwide.
What is Pipeline Integrity?
• The ability of a pipeline to operate safely, reliably, and efficiently.
• Involves design, construction, operation, inspection, and maintenance
practices.
Why is Pipeline Integrity Important?
• Safety: Prevents catastrophic failures, explosions, and environmental hazards.
• Reliability: Ensures uninterrupted supply of hydrocarbons and reduces
downtime.
• Environmental Protection: Prevents leaks and spills that could damage
ecosystems.
• Regulatory Compliance: Aligns with industry standards (API 1160, ASME
B31.8S, NACE, etc.).
