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.

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.

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.

MATCOR Ships Over a Half Million Feet of Linear Anodes to Africa

MATCOR shipped more than 500,000 linear feet of its SPL-FBR linear anode product for 153 above ground storage tanks at the Dangote refinery project in Lagos, Nigeria. MATCOR was selected for its rapid manufacturing capability and a no-field-splice anode design that reduces installation time and cost.

Tank Anode Systems for the Richest Man in Africa

MATCOR supplied tank anode systems for the $12 billion Dangote oil refinery project in Nigeria, which includes 153 above ground storage tanks on 6,180 acres outside Lagos. Engineer’s India Limited selected MATCOR’s impressed current linear anode technology as the design basis for tank bottom cathodic protection.

Specifying Sand Bedding to Support Above Ground Storage Tank Corrosion Protection

Proper sand bedding under above ground storage tank bottoms is critical to supporting effective cathodic protection and long service life. This article provides specifications for clean washed sand and explains why materials such as oil sand, crushed stone, or asphalt should be avoided under tank bottoms.

Corrosion Prevention in Aboveground Storage Tanks

MATCOR’s Ted Huck authored an article in BIC Magazine examining corrosion prevention best practices for aboveground storage tanks. The article compares grid anode and concentric ring cathodic protection configurations and reviews engineering considerations for effective tank bottom protection.

Quick Ship Cathodic Protection for Tanks

MATCOR’s Quick Ship program for tank cathodic protection maintains stock of its Tank Ring Anode System for rapid delivery when above ground storage tanks are unexpectedly taken out of service. Pre-assembled systems for tanks up to 200 feet in diameter ship from Chalfont, Pennsylvania with a two-day turnaround.

Tank Farm Design Recommendations for Corrosion Prevention

Tank farm design should account for corrosion risks to above ground storage tank bottoms based on site environment, tank size, and foundation type. This article provides recommendations and explains why cathodic protection is considered good engineering practice for tanks on sand or compacted soil foundations.
