2020 2021 budget as378401639 1

Trying to Complete 2020 CP Projects?

With Q4 2020 construction capacity filling quickly, MATCOR advises operators with remaining budgets to purchase cathodic protection materials before year-end for early 2021 installation, helping teams prepare for deferred project demand and upcoming PHMSA Mega Rule compliance requirements.

What is The Best Anode For Low Temperature Seawater Applications?

In low-temperature seawater environments, high localized chlorine concentrations around MMO anodes can affect current distribution and long-term coating wear rates. MATCOR offers a modified low-temperature MMO anode formulation that promotes oxygen generation over chlorine production to address these concerns in cold,…

Horizontal Directional Drilling for a Middle East Tank Retrofit

A Tanks & Terminals article details a Middle East ethylene storage tank cathodic protection retrofit where MATCOR’s horizontal directional drilling approach—installing linear anodes directly beneath the tank—succeeded after a conventional perimeter anode system failed to provide adequate current distribution across…

Better Tank Cathodic Protection

MATCOR’s article in Storage Terminals Magazine compares conventional grid anode systems to concentric ring linear anode systems for above-ground storage tank cathodic protection, explaining why premature grid system failures have caused excessive tank bottom corrosion and costly remediation.

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.

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…
Zerust vapor corrosion inhibitor

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.
cathodic protection budget 2019

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.

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.
