Linear flexbile anode designed for close by cathodic protection in
HDD applications
The flexible anode is also known as the polymer cable anode. The
polymer cable anode is made of conductive and stable modified
polymer. Graphite powder is used as the conductive material, and
the copper cable core is used as the current wire to make the
cable. The anode has good flexibility, strong resistance to
mechanical damage and good chemical stability. The outer diameter
of the cable is 12.7mm, and the cross-sectional area of the
internal copper core wire is 11.4mm2. Therefore, the resistance R'
per unit length is 2mΩ.m-1, and the flexible anode is mainly
Cathodic protection for buried pipes and tank bottoms. The original
intention of the development is to solve the serious aging of the
buried pipeline anti-corrosion layer, and the cathodic protection
current is significantly increased. It has been proved that the
application of the flexible anode successfully solves the problem
of the old pipeline cathodic protection, and can also generally
solve some traditional cathodic protection technologies.
Difficulties, such as interference with external structures,
problems with cathodic protection in high-resistivity environmental
media, and cathodic protection current distribution at the bottom
of the tank. Generally, a flexible anode generally has the
following components: a copper core, a conductive polymer anode
material, coke slag, a braid, and the like.
Copper core Linar anode for cathodic protection system
Flexible anode is the core component of cathodic protection system.
It is linear , flexible and carbon based anode system, being
installed in the pipeline, tanks, or other protected structure
nearby, and connected to the anode which is connected with external
powder supply, while the oil tank and pipeline are connected to the
negative electrode of the external powder supply to form a
circuit.After power on, the right amount of protection current can
be evenly dispersed through the wire to each poart so that the
protected body is fully protected.
The application of flexible anode successfully resolves the problem
of old pipeline cathodic protection and also can generally solve
the difficulty of some convential cathodic protection technology
such as interference of external structure, the inimplemen tation
of cathodic protection problems in high resistivity envitonment
medium,cathodic protection current distribution at tank bottom.
