Solid MMO Ribbon Manufacturer · Tank-Bottom ICCP
HELE supplies solid MMO-coated titanium ribbon and titanium conductor bars for distributed tank-bottom cathodic-protection grids. Ribbon size, spacing, grid geometry, crossover connections and design-life basis are reviewed as one system boundary.
Engineering boundary: Solid ribbon is not expanded mesh ribbon. Compare quotations only after ribbon geometry, conductor-bar layout, backfill, current duty and connection inspection are aligned.
A solid MMO ribbon anode is a continuous flat titanium strip coated with mixed metal oxide and used as the active anodic element in distributed impressed-current cathodic-protection systems.
A continuous solid titanium ribbon with an MMO active coating, typically arranged in parallel runs to distribute protection current across the designed area.
An open mesh-form MMO electrode with a different exposed-area and installation geometry. It should be specified separately from solid ribbon.
Ribbon width, thickness, active surface area, coil length and electrical duty should be reviewed together because they influence grid layout, current distribution and the project design-life basis.

| Model | Linear Resistance | Reference Current Output | Design-Life Basis |
|---|---|---|---|
| HL-MMO-A01 | 0.138 Ω/m / 0.04 Ω/ft | 17 mA/m / 5.2 mA/ft | Up to 50 years under rated project conditions |
| HL-MMO-A02 | 0.069 Ω/m / 0.02 Ω/ft | 42 mA/m / 12.8 mA/ft | Up to 50 years under rated project conditions |
Reference current output and design life must be confirmed against the specified MMO coating, backfill or contact environment, ribbon spacing, current duty and project design criteria. These values should not be treated as an unconditional field-life guarantee.
Tank-bottom ICCP systems can use parallel solid MMO ribbon runs interconnected by transverse titanium conductor bars to create a distributed anode grid beneath the protected tank bottom.
The MMO-coated ribbon is the active anodic element that distributes protection current across the designed tank-bottom area.
The conductor bar electrically interconnects ribbon runs and forms part of the grid current-distribution network.
Ribbon spacing is reviewed against tank geometry, protection-current demand, backfill condition and the required current-distribution pattern.
Ribbon-to-conductor-bar intersections require reliable electrical continuity and mechanical integrity according to the approved grid design.
Ribbon size, ribbon spacing, conductor-bar layout, electrical duty and connection arrangement can be reviewed around the tank geometry, backfill condition and cathodic-protection design.

Send Your Tank CP Design DataElectrical continuity at ribbon-to-conductor-bar crossover points is important to the completed grid. Connection method and inspection requirements should follow the confirmed project and production specification.
Ribbon width, thickness, active length and required grid position are reviewed against the agreed drawing and order specification.
Ribbon-to-conductor-bar connection points are produced according to the confirmed joining method and project grid specification.
Continuity and other agreed project-specific electrical checks can be included according to the inspection scope.
Connection location, ribbon dimensions, identification, surface condition and required project records are reviewed before shipment.
Documentation can be prepared according to the agreed purchase and inspection requirements.

Before Requesting a Quote
Solid MMO ribbon is selected as part of an electrical grid or distributed-anode layout. Width and thickness matter, but the project also needs a stated linear-output basis, conductor-bar arrangement and controlled joint details.
Compare the adjacent product families only after the reaction, environment and supply boundary are clear.
Inside HELE
Ribbon width, thickness, coated surface, coil identity and crossover connections are controlled against the approved grid schedule. Where conductor bars or prefabricated sections are supplied, the inspection scope can include dimensions, joining records, continuity and identification.
Confirm titanium form, grade or order standard, dimensions and material evidence against the purchase specification.
Control the coating direction and active geometry to the agreed production basis; do not infer life from appearance alone.
Review electrical joints, cable or conductor interfaces, sealing and mechanical details included in HELE’s supply scope.
Verify dimensions, identification, visual condition, packing and the agreed inspection or document package before shipment.
Sampling, acceptance values, test methods and supplied records are finalized in the quotation, inspection plan or approved order documents.
