Does an MMO flexible anode have nodes?

MMO flexible anode node is a point of 3 meters. The basic structure of the flexible anode is: internal anode core material + filled coke powder + external wrapping fabric + external mechanical woven protective net. Because of its flexible bending, it resembles a thick cable and becomes a flexible anode or cable anode.

Flexible anodes have the following 10 advantages:

High quality noble metal oxide MMO coated anode wire, with high current impact resistance, long service life, high discharge line density advantages;

2, parallel copper core double insulating layer conductive cable parallel conductive cable is double insulation sheath, the outer sheath is PVC sheath, with acid resistance, oxidation resistance and long service life advantages;

3. In addition, the copper core of conductive cable with sufficient cross-sectional area can fully meet the requirements of anode current carrying capacity and current attenuation;

4. Special anode filled coke with high conductivity and high carbon content and special chemical treatment can effectively extend the service life of MMO anode core wire, reduce ground resistance and increase discharge density;

5, wrap acid-resistant fabric with a certain water permeability, air permeability of the wrap fabric, the coke packing densely wrapped around the anode core, ensure the dimensional stability of the flexible anode, and the integrity of the flexible anode during the use of;

6, external mechanical braided protection mesh layer wear resistant, high strength braided mesh layer can provide good mechanical protection for flexible anode inclusion, to prevent mechanical damage caused by dragging during construction.

7, the arrangement is simple, flexible and flexible anode can be laid directly close to the pipeline, directly implement the protection of the pipeline, greatly reduce the current loss, improve the protection of current use efficiency. At the same time, because the flexible anode is pre-packed with high quality special coke packing, the installation can be directly buried, eliminating the laying of coke packing process, greatly reducing the construction workload. At the same time, because the flexible anode can be flexible bending, can adapt to the complex shape of the protected object, to achieve high efficiency of targeted protection.

8, small stray current interference due to close to the protected object buried, can minimize the stray current interference to other metal structures, to avoid additional losses;

9. High discharge density, low grounding resistance, high discharge density and long service life. At the same time, due to the long distance laying characteristics of the flexible anode, the protection of the pipeline can achieve a low grounding resistance, which is conducive to reduce the output of the system, improve the economy of cathodic protection.

10, the MMO anode used in flexible regional cathodic protection technology advantages regional cathodic protection refers to a particular factory (such as oil QiZhan, petrochemical refinery plant, power plant, etc.) within the scope of the buried metal facilities, such as: the process piping, fire pipeline and other ground system, unified implementation of cathodic protection cathodic protection technology. It is difficult to adopt the traditional distributed anode protection technology. To ensure the success of the project, the design and construction personnel have rich experience and high technical level. It is often necessary to adopt measures such as "step-by-step construction". Even so, it is difficult to ensure the uniform potential distribution of all protected objects and completely avoid the occurrence of "interference and shielding" problems. Because of the technical advantages of flexible anode, the problem of "interference and shielding" can be effectively avoided. At the same time, the difficulty of design and construction is greatly reduced, and the success rate of project implementation is easy to be guaranteed. At present, it has become a technical trend to use flexible anodes for regional cathodic protection in complex network stations.
