MMO Linear Anodes
Distributed-current assemblies for long pipelines, tank bottoms and applications requiring current along a defined route.
View ProductTubular, canister, wire, linear, ribbon, mesh, disc and custom MMO titanium anodes manufactured to approved CP design inputs for pipelines, tanks, marine assets, offshore structures and reinforced concrete.
HELE supplies anode components and specified assemblies. Final CP system design, rectifier selection, interference control and commissioning remain within the qualified CP designer or EPC scope unless contractually included.

An impressed current cathodic protection system uses an external DC power source to drive protective current from the anode, through the electrolyte and onto the protected structure.
The anode is one engineered component within a complete system that can also include a rectifier, reference electrodes, cabling, junction boxes, monitoring and control equipment.
HELE manufactures the MMO titanium anode component and specified assembly to customer-approved drawings and design inputs. Current demand, voltage, anode quantity, placement and protection criteria must be established by the responsible CP designer.

This matrix is procurement navigation, not a substitute for a project-specific cathodic-protection design.
| Application | Forms commonly reviewed | Inputs that control selection |
|---|---|---|
| Pipelines / distributed groundbeds | Linear, wire, tubular, canister | Soil resistivity, coating condition, current demand, route and installation method |
| Tank bottoms | Linear, ribbon, mesh ribbon, canister | Foundation condition, layout, current distribution and access |
| Marine / offshore | Tubular, disc, custom assembly | Seawater chemistry, mounting, current, cable protection and inspection access |
| Reinforced concrete | Ribbon, mesh ribbon, discrete anodes | Concrete resistivity, chloride exposure, layout and embedment details |
| Water / process equipment | Tubular, rod, disc, custom | Chemistry, temperature, geometry, current and connection design |

Structure type, geometry, coating condition and exposed area.
Seawater or process chemistry, soil or concrete resistivity, temperature and operating conditions.
Required current, voltage basis, active area, anode quantity and rated conditions.
Target design life, anode placement, groundbed, backfill, mounting and access.

Claim rule: no current-output or design-life statement is a project guarantee unless the rated environment, active area, coating/loading, current density, cable/seal and acceptance basis are stated.
Uses an external DC source and controlled output. It is commonly evaluated for larger, higher-current or adjustable systems and requires design, monitoring and commissioning.
Uses the natural potential difference of zinc, aluminum or magnesium anodes without a rectifier.
