Cathodic Protection Remote Monitoring
Cathodic protection remote monitoring systems allow pipeline operators to continuously oversee CP and AC mitigation performance without dispatching technicians to remote locations. This article covers the equipment, features, and data transmission methods common in modern CP remote monitoring deployments.
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.
New Drilling Trucks!
MATCOR has added three new drilling trucks to its equipment fleet to support cathodic protection installation in the mid-continent and Gulf regions. The trucks feature upgraded rotary speed and torque controls, satellite maintenance tracking, and improved operator safety platforms.
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.
Zinc Ribbon Installation Projects
Two MATCOR AC mitigation projects highlight zinc ribbon installation capabilities in challenging environments. The first used horizontal directional drilling in a congested northwestern Ohio corridor, while the second employed specialized rock trenching equipment at a highly rocky site in West Texas.
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.
Matcor Earns Patent for Iron Gopher® Linear Anode
MATCOR earned a design patent for its Iron Gopher® linear anode, the only linear anode designed for horizontal directional drilling. Featuring a braided stainless steel jacket and built-in pulling loop, the Iron Gopher provides approximately 200 percent more pulling strength than conventional HDD anodes.
AC Mitigation Video | Overview of Goals, Strategies and Materials
This nine-minute training video covers the goals, strategies, and materials used in pipeline AC mitigation. Topics include reducing fault condition current density, maintaining safe step and touch potentials below 15 volts, and using AC modeling to evaluate mitigated and unmitigated interference conditions.
Leak Detection and Repair
Leak detection and repair (LDAR) programs monitor petrochemical process equipment for fugitive emissions of volatile organic compounds. This article reviews applicable regulations and presents a five-step framework for developing effective LDAR programs at refinery and industrial facilities.
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.
