MMO/Ti Flexible Anode
Introduction To Product
Basic structural components: Internal cables, MMO wires, pre-filled calcined petroleum coke powders, fabric coating layers and long fiber braid.
Internal cables: no-stop inner cables provide stable current for the anode; and 13 strands of copper wires are hinged to ensure the flexibility.
MMO wires: as an anode body, it is a mixture of iridium/tantalum oxide coated on the surface of titanium wires.
Calcined petroleum coke powders:
- The maximum run current density with cokebackfill in soil environment;
- The contact resistance between the auxiliary anodeand soil is reduced;
- Electrochemical reaction is performed between the carbon powder around the auxiliary anode (conductive polymer or MMO/Ti wire) and soil electrolyte, so as to prevent the protected matters from being subjected to electrochemical corrosion and prolong the service life of the auxiliary anode.
Fabric Jecket:
- The carbon powder shall be coated around the anode in a circular shape and with a certain filling density, so as to make the carbon powder not moved, loosened and dropped off in the process of storage and transportation, construction and use to affect the normal use and service life of the flexible anode.
- It shall have excellent wear resistance, puncturing resistance and mechanical strength;
- It shall have corrosion resistance, which is very important to apply under water.
Protective braid:
- During construction and erection, the textile coating shall be prevented from wearing by the flexible anode, so as to further restrain and fix the carbon powder and the fabric coating.
- It shall have excellent wear resistance and mechanical strength;
- It shall have corrosion resistance, which is very important to apply under water.
The structure of Conductive Polymer lexible anode
Product Usage
- Cathode protection of buried steel long-distance pipelines (oil, gas and water);
- Cathode protection of large-scaled steel storage tank floor；
- Cathode protection of dense pipeline regions, such as stations, power plants and chemical plants.
Features of product
- Protect uniform distribution of current;
- Minimum impact on surrounding metal structures;
- Cause no shielding and interference in complicated pipeline dense regions;
- The flexible anode can be cut freely according to the needs of the protected matters at the construction site and is convenient and flexible to use;
- The protection effect is good, especially for complicated pipelines, old pipelines, storage tank floors, high-resistivity environments, etc, and cannot be exceeded by that of other anodes;
- The flexible anode will not cause environment pollution.
