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.

Does Cathodic Protection Cause a Tank Bottom to Dry Out?

A stoichiometric analysis of cathodic protection reactions shows that a typical CP system on a 150-foot diameter above-ground storage tank consumes approximately 10% of sand bedding moisture over a 30-year operating life, indicating that significant foundation drying from CP is unlikely.

What is the Carbon Footprint of Deep Anode Systems?

A stoichiometric analysis shows that a typical 50-amp deep anode cathodic protection system generates a maximum of approximately 180 kg of CO2 per year—roughly 4% of annual passenger vehicle emissions—through electrochemical reactions in the coke backfill column.

AC Corrosion Criteria: What It Is & How to Identify It

NACE SP21424-2018 establishes AC corrosion control criteria for cathodically protected pipelines based on time-weighted AC and DC current densities, with thresholds that vary depending on whether DC current density is controlled below 1 A/m².

Impressed Current Sled Anodes for Marine Structures – FAQs

This FAQ addresses common questions about MATCOR’s impressed current sled anode systems for marine structures, covering water conductivity effects on system design, comparisons with galvanic anodes, cable protection methods, marine wildlife considerations, and provisions for dredging operations.

Private: New Office in Western PA

MATCOR has opened a new field service and sales office in Bentleyville, Pennsylvania to support cathodic protection and corrosion control projects throughout Western Pennsylvania, West Virginia, and the Ohio Valley.

Rethink Your Shallow Horizontal Anode Bed Design – The Case For Linear Anodes

Continuous linear anodes offer significant advantages over conventional multi-anode shallow horizontal anode beds, including factory-assembled reliability, fewer field splice connections, compatibility with horizontal directional drilling installation, and lower overall installed cost per amp-year for mixed metal…

Replaceable Anode System Success: A First for Critical Middle East Tank Assets

MATCOR completed the first horizontal directional drilling tank cathodic protection installation in the Middle East, deploying a replaceable linear anode system beneath a critical ethylene storage tank at Equate Petrochemicals in Kuwait after a perimeter anode approach failed to meet NACE criteria.

Vapor Corrosion Inhibitors

Vapor Corrosion Inhibitors (VCIs) protect metal surfaces by diffusing through confined spaces and forming a molecular barrier against moisture and oxygen. This guide covers VCI applications for pipelines and storage tanks, monitoring methods, relevant industry standards, and MATCOR’s partnership with Zerust® Oil & Gas.

MATCOR is Hiring!

MATCOR is actively recruiting as the company expands operations in the Gulf Coast, Permian Basin, and Rockies regions, adding new drilling rigs, Mud Puppy filtration systems, and water trucks to meet growing cathodic protection service demand.

Have Extra 2019 Budget Monies?

MATCOR recommends using remaining 2019 cathodic protection budget funds to purchase materials—including Mitigator® AC mitigation wire, SPL™ linear anodes, Durammo® deep anode systems, and MMP™ canister anodes—before year-end for installation in early 2020.

Case Study: AC Mitigation Design Criterion – It Matters

On a 200-mile pipeline project with 41 high-voltage AC collocations, changing the AC mitigation design criterion from 30 A/m² to 50 A/m² and refining input data reduced parallel mitigation requirements by nearly 50 miles, illustrating how criterion selection significantly affects project scope and cost.

AST Cathodic Protection System Tank Isolation Considerations

Electrical isolation of above-ground storage tanks from connected piping and grounding systems is an important design consideration for cathodic protection, particularly for deep anode systems prone to significant current losses.
