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.

New Pipeline Cathodic Protection Design | 12 Things to Consider

Designing cathodic protection systems for new pipelines requires attention to a broad set of factors beyond basic CP principles. This article outlines 12 key considerations—including soil resistivity, pipeline routing, coating type, and operating conditions—that CP designers should address during the design phase.

Soil Resistivity Testing

Soil resistivity is a primary design parameter in cathodic protection engineering, influencing anode selection, quantity, and configuration. This article describes common soil resistivity testing methods and guidelines for collecting accurate field data to support effective CP system design for buried structures.

Anode Current Ratings and Soil Resistivity

Anode current ratings are based on expected service life in amp-hours, not soil resistivity, which only affects circuit resistance. This article explains anode life calculations for magnesium and mixed metal oxide anodes and clarifies the distinction between current rating and operating resistance.

6 Sled Anodes Replace 274 Galvanic Anodes for Marine Jetty Corrosion Protection

MATCOR’s Sea-Bottom impressed current anode sleds protected a steel pile jetty in Indonesia, replacing a galvanic design that would have required 374 aluminum anodes. Six sled anodes were installed in three days, demonstrating a cost-effective alternative to galvanic cathodic protection for marine structures.
