PIPE-MOUNTED SACRIFICIAL ANODES

Bracelet Anodes for Subsea Pipelines

Custom half-shell, segmented and full-ring bracelet anodes manufactured around pipe outside diameter, coating system, concrete weight coating and approved installation drawings.

A usable bracelet-anode quotation requires the pipe and coating OD, alloy, net anode mass, width, core geometry, clearance, fastening method, current demand and design life.

PRODUCT DEFINITION

Bracelet Anodes Engineered Around the Pipeline

Bracelet anodes distribute sacrificial alloy around a cylindrical asset while maintaining the specified clearance, installation interface and hydrodynamic profile. Geometry must be coordinated with bare pipe OD, anti-corrosion coating, concrete weight coating, field-joint details, steel core, segment connection and installation sequence.

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

A bracelet anode must fit the actual coated pipeline and installation sequence. A nominal pipe diameter does not define the inside clearance or field-joint interface.

01

Pipeline build-up

Send bare pipe OD, anticorrosion coating OD, concrete weight coating and field-joint dimensions.

02

Segment geometry

Define half-shell or ring construction, inside and outside diameters, width, gap and tolerance.

03

Core and connection

Show cast-in core, lifting and attachment details, welding ears or clamps and required electrical continuity.

04

Transport and acceptance

Agree segment identification, dimensional fit-up checks, net alloy mass and packing to protect the installation faces.

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

Bracelet casting is controlled by the approved pipe-interface drawing, alloy, steel core and segment dimensions. HELE can check net alloy weight, fit-up dimensions, continuity and identification before the halves are packed for the installation sequence.

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 pipe OD, coating and concrete-weight-coating OD, subsea or onshore service, alloy, net anode mass, split or full-ring layout, width and profile, steel-core drawing, approved current demand, design life, quantity and installation schedule.
