E.36.HG – When Inhibitor Programs Aren’t Enough - A Crude Pipeline Corrosion Case Study

Описание: Case Study: Unexpected Corrosion in Modern Crude Oil Pipeline

In this episode of the Trusted Pipeline Advisor Podcast, we explore a surprising case study where a modern crude oil pipeline exhibited severe internal corrosion far earlier than predicted.

Despite having a robust corrosion inhibitor program, this 10-mile, 10-inch diameter pipeline began to show over 50% internal metal loss within just five years.

The culprit was a combination of complex flow behavior, production tie-ins, and the ingress of debris and oxygen at tie-in points.

Discover how mechanistic flow modeling and adaptive interventions, including the addition of oxygen scavengers and improved monitoring, helped identify and mitigate the issue, highlighting the importance of continual monitoring and timely response in pipeline integrity management.
