Packaged Magnesium Anodes
Available to the specified alloy, dimensions, net mass, attachment details, inspection scope and approved project drawing.
SOIL AND FRESHWATER CATHODIC PROTECTION
Magnesium Sacrificial Anodes for Cathodic Protection
High-potential and standard-potential magnesium anodes for buried pipelines, underground tanks, utilities, freshwater structures and temporary cathodic protection.
The required driving voltage and anode output depend on soil or water resistivity, structure potential criteria, coating condition, backfill, spacing and approved CP calculations.

PRODUCT DEFINITION
Choose Magnesium Anodes by Potential and Environment
Magnesium is commonly considered where higher driving voltage is required, especially in soil and freshwater. High-potential and standard-potential alloys are not interchangeable by label alone. Selection requires the specified alloy chemistry, potential range, capacity, resistivity, current demand, design life, package backfill, cable and installation arrangement.
Engineering Review Starts With Inputs
- ✓ Protected asset and environment
- ✓ Coating condition and exposed area
- ✓ Current demand and design life
- ✓ Alloy and electrochemical criteria

TECHNICAL SPECIFICATION
Parameters to Confirm Before Purchase
Use project-specific values. A generic catalogue value is not a substitute for the approved cathodic-protection calculation or purchase specification.
| Alloy type | High-potential or standard-potential magnesium alloy to the project specification. |
|---|---|
| Potential | Open- and closed-circuit values stated with reference electrode, electrolyte, temperature and test method. |
| Capacity and efficiency | Electrochemical values tied to a named test method and acceptance criteria. |
| Size and mass | Net magnesium weight, casting dimensions, core details and allowable tolerances. |
| Backfill and package | Backfill composition, bag dimensions, moisture condition and package weight where required. |
| Cable and connection | Cable type, length, cross-section, insulation, anode connection and sealing details. |

MANUFACTURING AND QA
Control the Drawing, Alloy, Mass and Interface
Manufacturing review should confirm alloy charge control, mould and core arrangement, insert preparation, casting condition, dimensions, net mass, electrical continuity, marking and packing.
Inspection and document scope must be agreed in the purchase order. Any potential, capacity, efficiency or service-life statement should identify the governing test or calculation conditions.
Available Documentation by Order Scope
• Approved production drawing
• Alloy or chemistry record
• Net-weight inspection
• Dimensional inspection
• Insert or cable continuity
• Marking and packing record
• ITP and witness records
• Project-specific certificates

FAQ
Technical and Procurement Questions
How is the correct anode type selected?+
Selection must start from the protected asset, electrolyte or soil, resistivity, temperature, coating condition, approved current demand, target life, governing specification and installation constraints.
Can HELE manufacture to a customer drawing?+
Yes. Manufacturability can be reviewed against the approved alloy, net mass, dimensions, insert or core, cable, mounting, tolerances, marking and inspection scope.
What performance values should be specified?+
State the required potential, capacity or efficiency together with the alloy standard, test method, electrolyte, temperature, duration and reference-electrode scale. Unqualified values are not directly comparable.
What determines service life?+
Service life depends on actual current demand, coating condition, environment, alloy capacity, utilization factor, net anode mass, anode resistance, placement and electrical continuity.
What quality documents are available?+
Depending on the purchase order, the document package can include approved drawings, alloy or chemistry records, weight and dimensional inspection, continuity checks, marking, packing and agreed ITP records.
What should I include in an RFQ?+
Provide the protected structure, soil or freshwater conditions, measured resistivity, coating condition, approved current demand, target life, alloy potential type, anode size and mass, backfill requirement, cable specification, quantity and installation drawing.
