AC Mitigation: 4 Approaches to Protect Your Assets

Pipelines paralleling high-voltage AC transmission lines require engineered grounding to prevent AC-induced corrosion and safety hazards. The four primary AC mitigation strategies—fault shielding, gradient control mats, lumped grounding, and gradient control wires—are detailed with design and monitoring guidance.

Cathodic Protection—What is it and how does it work?

What is cathodic protection? Understand the basics of cathodic protection. See how it extends the life of critical infrastructure.

Why the Durammo Deep Anode Groundbed System Doesn’t Need Centralizers

Learn why the Durammo™ Deep Anode System does not require centralizers and how its design differs from traditional HSCI anode installations.

Stray Current Corrosion: Common Types of Stray Current Interference

Learn how DC stray current corrosion, AC interference, and telluric currents contribute to stray current interference and CP challenges.

Why Cathodic Protection Fails in Power Plants (and How to Fix It)

CP systems often underperform in power plants due to grounding interference, isolation issues, and limited visibility. Learn why—and how to fix it.

Tank Cathodic Protection Testing: Overcoming Common Challenges

On the surface, applying cathodic protection to a storage tank appears straightforward. However, accurate tank cathodic protection testing is rarely that simple. The reality of validating tank bottom corrosion control is actually far more complex.

Three Methods for Corrosion Prevention of Buried Plant Piping in New Construction

Three cathodic protection approaches protect underground piping in congested plant environments: deep anode systems, shallow distributed anode beds, and linear anodes. For most plant applications, closely coupled linear anode systems provide the most technically effective and commercially viable solution.

An Age-Old Problem: Addressing Aging Pipeline Coating Threats

As pipeline coatings deteriorate, traditional CP systems struggle with current distribution and rising operating costs. MATCOR’s Ted Huck examines rehabilitation alternatives, including linear anode systems that saved over $1.5 million versus recoating on a 5-kilometer pipeline segment.

Protecting Aging Pipelines: Strategies for Coating Deterioration

As pipeline coatings age, external corrosion protection diminishes. A Materials Performance article highlights advanced cathodic protection systems and recoating solutions to extend pipeline service life while addressing soil stress and coating disbondment.

Pipeline Corrosion and Prevention—A Comprehensive Guide

This guide explains pipeline corrosion, the different types, and how to prevent it to avoid costly and dangerous failures.

Cased Pipeline Crossings and VCI [Rusty Talks]

Cased pipeline crossings present unique corrosion challenges for operators. This article explores the use of vapor corrosion inhibitors…

Enhancing Aboveground Storage Tank Protection: The Role of Vapour Corrosion Inhibitors (VCIs)

Vapour Corrosion Inhibitors (VCIs) provide an additional layer of corrosion protection for aboveground storage tank bottoms, addressing limitations of cathodic protection alone. MATCOR’s Ted Huck explores VCI application methods and monitoring in the Autumn 2024 Tanks & Terminals magazine.
