MMO-Coated Titanium Tubular Anodes for ICCP Systems
HELE manufactures bare, cable-connected, string and canister-ready MMO tubular anodes. Tube geometry, active coated area, environment, current-density basis, cable connection and sealing are reviewed together for the required ICCP duty.
Engineering boundary: The same tube does not carry one universal rating. Rated output must remain linked to active area, coating, electrolyte or backfill, temperature, operating duty and design-life basis.
MMO Tubular Anode Configurations
The MMO-coated titanium tube is the active electrode. It can be supplied in different electrical and mechanical configurations according to how the anode will be connected, installed and integrated into the cathodic-protection system.
Bare MMO Tubular Anode
MMO-coated titanium tube supplied as the active electrode for integration into the customer’s own CP assembly, mounting structure or project design.
Cable-Connected Tubular Anode
Tubular active element supplied with project-specific cable connection, protected termination and sealing requirements.
Tubular Anode String
Multiple tubular active elements can be assembled into a project-specific anode string where the confirmed cathodic-protection design requires distributed connected elements.
Canisterized MMO Configuration
A tubular active element may also be incorporated into a prepackaged canister with conductive backfill. This is a separate packaged product configuration.

Tube diameter, total length and active coated length define the physical geometry of the tubular electrode and should be reviewed together with the required active surface area, electrical duty and installation configuration.

Rated Output Depends on the Operating Environment
The same tubular-anode geometry does not have one universal output rating. Current density and rated output must be linked to the active geometry, MMO coating requirement, contact environment and design-life basis.

Note: Reference current output and design life apply to the stated design basis. Final ratings should be confirmed against active coated geometry, MMO coating requirement, electrolyte or backfill condition, temperature, operating duty and project requirements.
Active Surface Area, MMO Coating & Electrical Duty
Tubular-anode performance is defined by more than tube diameter. Active coated length, exposed cylindrical surface, MMO coating requirement, operating environment and current-density basis should be evaluated together.
Tube Geometry
Diameter · Length · Active Zone
Active Coated Area
The project active area should be based on the confirmed tube geometry and coated length used for the electrical design.
MMO Coating
Coating family and coating requirement should be selected according to the electrochemical environment and specified duty.
Electrical Duty
Current density and total output per anode should remain linked to the approved environmental and design-life basis.
Cable Connection, End Cap & Sealing
For cable-connected tubular anodes, the electrical interface and termination should maintain continuity while protecting the internal connection against mechanical damage and environmental ingress.
Electrical Connection
The internal connection between the tubular titanium electrode and lead conductor should follow the confirmed assembly and electrical requirements.
End Cap & Termination
End construction can be configured around the required cable connection, sealing and mechanical installation arrangement.
Cable System
Cable insulation and supplied length should be selected according to installation environment, electrical duty and project specification.
Sealing & Inspection
Cable connection, sealed interface and project-specific electrical checks can be included according to the agreed inspection scope.
Where MMO Tubular Anodes Are Used
Groundbed Cathodic Protection
Bare or cable-connected tubular anodes can be integrated into engineered deep or shallow groundbed arrangements according to soil conditions, backfill and required current.
Seawater & Marine ICCP
Tubular MMO electrodes can be reviewed for seawater and marine cathodic-protection applications when coating, electrical duty, cable system and mounting are matched to the environment.
Freshwater & Water Intake Systems
Tubular configurations can be reviewed for suitable freshwater and water-intake applications according to conductivity, chemistry, active area and required current.
Tanks, Pipelines & Buried Structures
Tubular anodes can be incorporated into project-specific ICCP systems where a compact cylindrical active electrode is required.
Installation Note: Placement, mounting, cable routing, mechanical protection, contact environment and anode spacing should follow the approved cathodic-protection system design.

Tubular Anode vs Rod Anode vs Canister Anode
| Product | Construction | Main Selection Direction |
|---|---|---|
| MMO Tubular Anode | Hollow cylindrical MMO-coated titanium active electrode | ICCP systems requiring tubular active geometry, cylindrical surface area and flexible connection options |
| MMO Rod Anode | Solid rod-shaped MMO active electrode | Compact rigid electrode geometry and project-specific localized installation |
| MMO Canister Anode | MMO active element + conductive backfill + canister + cable | Installation-ready deep or shallow groundbed assembly |
Note: A tubular anode is the active electrode form. A canister anode is a packaged groundbed assembly that may use a tubular active element internally.
