Product Introduction
Tubular Titanium MMO Anode
It is a type of anode used in electrochemical processes, typically for the production of chlorine or caustic soda. It is made of titanium and is coated with a mixed metal oxide (MMO) material.Since 2001, Changsheng Titanium has started to export the tubular titanium MMO anode supply. It has a history of more than 20 years.
Tubular Titanium MMO Anode can be utilized as helper anodes for applied ebb and flow cathodic security in seawater, freshwater, soil and cement natural media. Homegrown and unfamiliar cathodic insurance designing practice shows that this new anode material enjoys numerous extraordinary benefits. However, when using MMO coated titanium anodes, the following considerations must be made to ensure a sufficient level of protection:
(1) The formulation of the MMO coating ought to be reasonably selected in accordance with the protective environment.
(2) When making an MMO coated titanium anode, strict quality control should be done on things like the coating thickness, uniformity, and bonding between the coating and the titanium substrate, among other things. ought to meet specific necessities to guarantee the best anode execution.
(3) To prevent moisture intrusion, the MMO coated titanium anode and wire connection should have low resistance and good watertightness.
(4) The wire ought to resist corrosion and provide effective insulation.

Application Case
Tubular titanium MMO (Mixed Metal Oxide) anodes are commonly used in a variety of applications where corrosion protection is critical, such as in the cathodic protection of steel structures, pipelines, and storage tanks in the marine, offshore, and industrial sectors.
One example of the application is in the protection of underground pipelines used for the transportation of petroleum products, natural gas, or water. In these applications, the anodes are installed along the length of the pipeline and connected to a DC power source. The anodes work by providing a cathodic current that counteracts the natural tendency of the steel pipeline to corrode in the soil environment. By supplying electrons to the pipeline, the anodes protect it from corrosion and extend its service life.
Another example of the use of it is in the protection of reinforced concrete structures such as bridges, parking garages, and buildings. In these applications, the anodes are embedded in the concrete and connected to a power source. The anodes work by providing a protective current that counteracts the natural tendency of steel reinforcing bars to corrode in the presence of moisture and chloride ions. By supplying a protective current, the anodes prevent corrosion and extend the service life of the concrete structure.
