MMO/Ti Flexible Anode
Continuous flexible auxiliary anode using MMO-coated titanium elements, flexible internal cable construction and factory-filled calcined petroleum coke backfill for suitable impressed-current cathodic protection installations.
Flexible anode for complex steel structures
The manufacturer describes this product as a flexible anode assembled from internal cables, MMO-coated titanium wires, calcined petroleum coke powder, a fabric coating layer and an outer long-fiber braid.
Its flexible form is intended to make installation practical where protected structures have complex geometry or where a distributed anode arrangement is advantageous.
Product structure
Why the construction matters
- The flexible form can follow complex installation routes.
- Carbonaceous backfill is used to reduce contact resistance around the auxiliary anode.
- The textile layers retain the backfill and protect the anode assembly during handling and installation.
- MMO/Ti technology provides the electrochemical anode element; the complete system still requires project-specific design.
Typical applications published by OuChuang
Buried pipelines
Long-distance buried steel pipelines for oil, gas and water applications.
Storage tank floors
Large steel storage tank floor structures where a distributed flexible anode arrangement is appropriate.
Dense pipeline areas
Stations, power plants and chemical plants with complex or closely spaced buried metallic structures.
Published product features
- Current distribution described as uniform.
- Low impact on surrounding metal structures when the system is properly designed.
- Suitable for complicated pipeline regions where shielding and interference must be considered.
- Flexible installation and site cutting are described by the manufacturer.
- Published applications include complex pipelines, older pipelines, tank floors and higher-resistivity environments.
Selection must be project-specific
For pipeline CP, the current ISO edition is ISO 15589-1:2026. It covers surveys, design, materials, equipment, installation, commissioning, operation, inspection and maintenance for cathodic protection of on-land pipeline transportation systems.
Do not select an anode solely from a catalogue current rating. The CP system should be designed from the protected surface area, coating condition, electrolyte characteristics, electrical continuity/isolation, current demand, anode-bed arrangement and applicable project criteria.
