Magnesium Ribbon Anode for Cathodic Protection
Magnesium ribbon anode is specifically designed for cathodic protection in high resistivity environments such as soil and fresh water, as well as in confined spaces where traditional anodes are difficult to install. Its typical applications include long-distance buried pipelines, the inner walls of pipeline casings, large storage tank bottoms, pipe networks, and underground cables.
Overview
Implementing standards
GB/T17731-2009 Magnesium Alloy Sacrificial Anode.
GB/T21448-2008 Technical Specification for Cathodic Protection of Buried Steel Pipelines.
Main Parameters
Material: High-purity magnesium (e.g., >99.95% Mg)
Electrochemical Capacity: Typically > 1200 Ah/kg
Open Circuit Potential: Approximately -1.7V vs. CSE (for high potential alloy)
Current Output: High current output per unit weight due to large surface-area-to-mass ratio.
Standard Sizes: Available in various widths, thicknesses, and coil lengths.
Product Features
High Current Output: The unique ribbon shape provides a large surface-area-to-mass ratio, enabling it to deliver a higher current output compared to conventional cast anodes of the same weight.
Flexibility & Easy Installation: The anode is extruded, making it flexible and easy to bend. This allows for simple installation in narrow, complex, or hard-to-reach spaces (e.g., inside casings, around pipe bundles).
Adaptability to High Resistivity: Specially formulated and designed to perform effectively in high resistivity environments like dry or rocky soil.
Cost-Effective Engineering: Requires less installation space and can reduce overall engineering complexity and cost, especially in retrofit or confined situations.
Continuous Conductive Core: The integrated steel core ensures excellent conductivity along the entire length and minimizes connection points.
Detailed Application Scenarios
Buried Pipeline Networks: Primary protection for long-distance oil, gas, and water pipelines in soil.
Tank Bottom Protection: Laying under or around large above-ground storage tank (AST) bottoms.
Internal Protection: Inside buried pipeline casings or within confined structures.
Grounding Grids & Cable Protection: For electrical substations and protection of underground power/communication cables.
Retrofit & Space-Constrained Projects: Ideal for situations where space is limited and traditional bulky anodes cannot be used.
