Because the mixed metal oxide titanium anode has the advantages that other anodes do not have, it has become the most ideal and the most promising auxiliary anode material in the field of cathodic protection.

Specific introduction:

Scope of application: it is mainly used for high resistivity environment, protection of pipe in casing, temporary cathodic protection of pipeline, protection of storage tank and pipe network, and ground gate to prevent strong electrical interference.

The strip anode is flat in shape, adjustable in length and easily bent.

Main function: the shape of the strip anode is flat, the length can be adjusted, easy to bend, good anti-corrosion function, do not need external DC power supply, automatic operation after installation, do not need maintenance, cover an area of less, low engineering use, and the external environment does not have any interference.

Implementation scale: ASTM B 843-1995 SY/T0019-1997

The dimensions of commonly used magnesium strip anodes are as follows:

The magnesium belt is mainly used in the coils of the protected body, the surface with narrow construction space, and the high resistivity soil, fresh water and other media.

The dimensions of common zinc strip anodes are as follows:

It can be used as grounding pole, release ac, lightning, equipment protection and personal safety. Mixed metal oxide anode in the ground bed at 100A/m2, working current density service life up to 20 years, its consumption rate is about 0.1mg/A.a, current density up to 5000A/ per square meter, the electrode will not be passivated and dissolved phenomenon, reliable function, low price.

The zinc strip anode can be used in freshwater and seawater environments, and can also be used in buried structures.

Main functions: good flexibility, easy installation, flexible, average current distribution, high current efficiency.
