Alloy and test basis
Name the alloy specification and the test method, electrolyte and reference-electrode scale behind any potential or capacity requirement.
MARINE AND OFFSHORE GALVANIC ANODES
Aluminum Sacrificial Anodes for Marine Cathodic Protection
Drawing-based aluminum alloy sacrificial anodes for ship hulls, ballast tanks, offshore structures, subsea pipelines and seawater equipment.
Anode alloy, electrochemical capacity, closed-circuit potential, net mass and geometry must be checked against the approved cathodic-protection design and service conditions.

PRODUCT DEFINITION
Aluminum Anodes Built Around the Approved CP Design
Aluminum sacrificial anodes provide galvanic current in seawater and selected brackish-water services. Product suitability depends on alloy chemistry, operating potential, electrochemical capacity, current demand, design life, anode resistance, utilization factor and installation geometry. HELE can review standard or custom castings against project drawings and inspection requirements.
Engineering Review Starts With Inputs
- ✓ Protected asset and environment
- ✓ Coating condition and exposed area
- ✓ Current demand and design life
- ✓ Alloy and electrochemical criteria
- ✓ Geometry and mounting interface
- ✓ Drawings, ITP and documentation
Project review
Confirm the Supply Basis Before Quotation
Marine alloy castings must match the approved CP calculation and the actual mounting drawing. The alloy designation alone does not establish current output or service life.
Net mass and geometry
Compare the specified net sacrificial-alloy mass, profile, exposed area and allowable casting tolerance—not only the model name.
Steel insert and attachment
Confirm welding feet, straps, brackets or bolt holes against installation drawings and electrical-continuity requirements.
Release documents
Set the required chemistry, weight, dimensions, continuity, marking and witness records before the production order is approved.

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 and standard | Specified aluminum-zinc-indium or other approved marine alloy; chemistry documented to the purchase specification. |
|---|---|
| Electrochemical performance | Capacity, efficiency and potential stated only with the applicable test method, electrolyte, temperature and reference-electrode scale. |
| Mass and geometry | Net and gross mass, dimensions, casting tolerance, exposed area and utilization allowance. |
| Insert and attachment | Steel insert, welding feet, strap, core, bracket or bolt-on details according to the approved drawing. |
| Service inputs | Seawater temperature, salinity or resistivity, coating condition, current demand and target design life. |
| Documents | Approved drawing, material records, weight and dimensional inspection, marking, packing and agreed ITP records. |

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
Inside HELE
Inside Our Manufacturing & Quality System
For drawing-based aluminum anodes, the approved alloy, mould, insert, net mass and attachment details are the manufacturing basis. HELE can agree the chemistry record, dimensional and weight checks, continuity test and packing identification for the order.
Alloy and casting
Confirm the approved alloy, core or insert, geometry and net sacrificial-alloy mass.
Electrical interface
Check continuity and the specified cable, weld or bolt attachment where the order requires it.
Inspection basis
Use the agreed methods and acceptance limits for chemistry, dimensions, weight and electrochemical evidence.
Order identification
Match markings, packing and release documents to the approved model and project schedule.
Final cathodic-protection design, installation and commissioning remain with the responsible project team unless expressly included in the contract.
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, seawater temperature and resistivity, coating condition, approved current demand, design life, alloy or standard, anode geometry, net mass, insert drawing, class or owner requirements, quantity and delivery schedule.
