MMO Coated Titanium Wire Anode For Deep Vertical Groundbeds Tanks Pipelines

MMO Coated Titanium wire anode for deep vertical groundbeds tanks pipelines

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.

Advantages :

Even distributed potential and current;

Construction Conveniently;

Less current loss;

More efficiency ;

Easy to bury anode bed;

No impact when rebuild the cathodic protection;

No more “interference, shield”problem;

Easy design and install.

MMO linear anodes, also known as flexible anodes, are an ideal product for use when a low-current, evenly distributed cathodic protection system is needed. The core of the anode is composed of high-grade, titanium wire with a Ir–Ta mixed metal oxide catalyst coating. The titanium wire is prepackaged in a porous, non-woven fabric “sock” that contains high conductivity calcined petroleum coke breeze —— enhancing the anodes abrasion and damage resistance.

The power cable attached is #10/#16 AWG stranded copper with either high molecular weight polyethylene (HMWPE) insulation or a dual insulation of Kynar/HMWPE. This cable has the capacity to maintain the required current over considerable distance without incurring substantial longitudinal voltage drop.

The MMO linear anode has the advantage of easy installation and handling as well being cost efficient. Typical uses for this anode include the impressed current cathodic protection of in-plant piping, buried oil (gas) pipelines, petrochemical container, tank bottoms and other underground structures.
