Product composition and structure
Basic composition: anode (copper core wire + conductive sheath), pre-filled material-petroleum calcined coke, textile cover layer, long fiber braid.
Copper core wire: The continuous copper core wire provides a stable current for the anode. In order to ensure flexibility, it is made of 133 strands of tinned copper wire double hinged.
Conductive sheath: as the main body of the anode, it has good conductivity, can protect the copper core wire from external corrosion, and at the same time draw out the protective current.
Calcined petroleum coke powders:
·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 the polymer flexible anode is as follows:
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
· Even protection current distribution;
· Minimal interference to surrounding metal structures;
· There is no shielding and interference in the dense area of complex pipe network;
· The flexible anode can be cut arbitrarily at the construction site according to the needs of the protected object, which is convenient and flexible to use;
· Good protection effect, especially for complex pipe network, old pipeline, storage tank bottom plate, high resistivity environment, etc., which is unmatched by other anodes;
· Flexible anode will not pollute the environment.
