News from MATCOR October 2025

Last month, we explored how Vapor Corrosion Inhibitors (VCIs) offer added protection where cathodic protection (CP) may fall short. But what if the risk isn’t just corrosion—but electrical interference?
This month, we’re spotlighting AC modeling—a powerful tool to assess and mitigate AC interference from nearby power infrastructure. Learn when it’s needed, how it works, and how to apply it effectively to protect your pipeline assets.

AC Modeling—The Basics
AC interference from high-voltage transmission lines can accelerate corrosion and pose a serious safety risk.
One of the most cost-effective ways to assess and mitigate this risk is through AC modeling, which typically follows four phases: data collection, creating the model, establishing criteria, and evaluating mitigation strategies.

4 Proven Approaches to AC Mitigation
When pipelines run parallel to high-voltage power lines, mitigation is essential—not optional.
Explore four field-proven AC mitigation techniques, when to use them, and how to select the right fit for your application.

Case Study: Why AC Mitigation Design Criteria Matters
In this real-world project, MATCOR modeled AC interference for a new pipeline and found that assumptions around design criteria had a major impact on the scope and cost of mitigation.
