Hele Titanium Engineering Team Reviewing Pipeline OD Data
Pipe-Mounted Sacrificial Anodes Built Around Pipeline Diameter and Design Life
Bracelet anodes are sacrificial anodes designed to fit around pipelines or pipe sections. They are commonly reviewed for offshore pipelines, subsea pipelines, risers, and marine pipeline systems where pipe-mounted galvanic protection is required.
Unlike general block or hull anodes, bracelet anodes must match the pipeline outside diameter, coating thickness, bracelet inner diameter, anode segment design, steel insert, anode weight, and installation method. The final material and size should be reviewed according to seawater or soil environment, project standard, current demand, design life target, and pipeline installation conditions.
Hele Titanium supports custom bracelet anodes in aluminum, zinc, and project-specific material options, with split / half-shell design, steel insert, clamp or welding structure, dimensions, weight, packing, labels, and documentation support according to project requirements.
1 Pipeline OD Matching
Bracelet ID, segment size, and installation clearance should match pipeline outside diameter and coating thickness.
2 Material Selection
Aluminum, zinc, or project-specified anode material can be reviewed according to environment and project standard.
3 Steel Insert Design
Steel straps, inserts, clamps, welding pads, or custom fixing structures can be designed by drawing.
4 Documentation
Inspection notes, material documents, packing list, labels, and project-specific documents can be prepared when required.
What Are Bracelet Anodes?
Bracelet anodes provide pipe-mounted galvanic cathodic protection for offshore pipelines, subsea pipelines, risers, shore crossings, and pipe sections exposed to corrosive environments.
Answer
Bracelet anodes are sacrificial anodes designed to fit around pipelines or pipe sections. They are usually supplied as split or segmented anode assemblies and electrically connected to the pipeline, allowing the anode alloy to corrode preferentially and help reduce corrosion on the protected pipe surface.
1. Why Suitable for Pipeline CP
Bracelet anodes are commonly selected for offshore, subsea, riser, and shore-crossing pipeline protection where pipe-mounted anode installation is required.
2. Compared with Block & Stand-Off Anodes
Bracelet anodes are designed to match pipeline outside diameter and coating thickness, while block or stand-off anodes are more commonly reviewed for structures, tanks, or marine equipment.
3. Why Alloy & Insert Design Matter
Aluminum, zinc, or project-specified alloy, together with steel insert, strap, clamp, or segment design, directly affects installation fit, electrical continuity, mechanical fixing, and service life.
4. How to Select the Right Bracelet Anode
Selection depends on pipeline outside diameter, coating thickness, bracelet inner diameter, anode weight, alloy requirement, steel insert design, installation method, design life target, and documentation needs.

When to Use Bracelet Anodes vs Other Sacrificial Anode Forms
Bracelet anodes are designed for pipe-mounted cathodic protection when the anode needs to fit directly around offshore, subsea, riser, or pipe-mounted structures. Other sacrificial anode forms may be more suitable for ship hulls, ballast tanks, underground pipelines, tank bottoms, or distributed soil CP layouts.

Installation Considerations for Bracelet Anodes
Proper installation helps bracelet anodes work as intended in pipeline cathodic protection systems. Pipeline fit, segment alignment, steel insert contact, coating clearance, electrical continuity, and mechanical fixing should be reviewed before installation.
| Installation Factor | What to Review | Why It Matters |
|---|---|---|
| Pipeline OD & Coating | Bracelet ID, pipe dimensions, and coating system | Ensures the bracelet anode matches the pipe to support correct fit. |
| Segment Alignment | Alignment of split or half-shell segments | Ensures segments align properly around the pipe during installation. |
| Steel Insert Contact | Steel insert or mounting structure | Supports reliable electrical connection to the protected pipeline. |
| Mounting Method | Clamp-on, weld-on, bolt-on, or project-specific fixing | Ensures the fixing method matches the required installation procedure. |
| Coating Clearance & Spacing | Pipe coating thickness, installation tolerance, and spacing | Proper spacing affects current distribution and protection coverage. |
| Mechanical Handling | Transport, pipe assembly, and offshore installation procedures | Prevents damage and ensures necessary inspection access is maintained. |
Buyer Note: Bracelet anode installation should be reviewed together with the full pipeline cathodic protection design. Share your pipe drawing, coating thickness, anode layout, and installation procedure for engineering review.
