Sea water is very corrosive environment because the salt present in it makes very good conductor of electricity. It creates a lot of free irons which accelerate oxidation of iron (mild steed) which made of oxidation.

MMO (Mixed Metal Oxide) coating disc anodes are used to protect the ship or boat hull from seawater corrosion. Normally titanium having non-corrosion nature, but non-conductive material. MMO coated disc used in ship hull protection to avoid the high corrosion in seawater.

MMO (Mixed Metal Oxide) coated disc anodes are used to protect the cathode from erosion and corrosion with DC power supply called as impressed current cathodic protection (ICCP).

MMO (Mixed Metal Oxide) coated disc size well be customized depends upon the design of the CP system.

Advantages:

• Ø  Increased life of rudders.
• Ø  Increased dry-dock interval.
• Ø  Automatic control equipment ensures reliable, simple operation.
• Ø  Durability compared to galvanic anodes.

Tianno manufacturing platinum as well as MMO coated disc. Below the product recently supplied to Netherland.

Platinized rod used in cantiliver anodes with active part of plating to protect the gigantic pump internals, suction, condenser box and pipelines etc.,

Platinum is an excellent catalyst due to its high conductivity and low consumption rate. Platinum deposition made by electroplating method over a high corrosion resistance substrate (Titanium). Since Titanium substrates is having non-corrosive nature form by insulating oxide film by platinum plantings.

Platinized titanium rod are usually used in cantilever anode which is used for protecting pipeline internals, suction and condenser box internal for 30 years and more by applying DC current with transformer rectifier. Normally titanium is well known for its high resistance to corrosion both water and chemical media but titanium is the poor electricity conductor. So we use platinum/ MMO plating/ Coating to increase the conductivity.

 Advantages:

• Ø  Low consumption rate that conserves precious platinum.
• Ø  Favorable dimensional stability.
• Ø  Corrosion resistance ensures durability with easy maintainability of the cathode to be protects.
• Ø  Light weight, as well as favorable current distribution in electroplating.

Tianno (Ti Anode Fabricators Pvt Ltd, Chennai, India) manufacturing and supplying platinized anodes and cathodic production based on titanium, niobium and other exotic metals. We produce a wide variety of standard and customized anode shapes to maximize your benefit. Below product is recently supplied to Saudi Arabia.  

Platinised rod is used for cantiliver anodes with active part of platinum plating to protect the gigantic pump internals and pipe lines.

Tianno manufacturing FRP insulated platinised rod and MMO coated rod for the cathodic protection of these structures. Below photo image of recently supplied to USA.

For the protection of ship or boat hull from seawater corrosion, we need to insert our MMO Coated titanium disc or Niobium disc or Platinized rubberized disc.

MMO COATED CANTILEVER ANODE FOR PUMP SUCTION/DISCHARGE

MMO Coated rod used to make the cantilever anode for the protection of pump internal protection, condenser box protection and more.

We the Tiaano supplying cantilever anodes as well as MMO Coated rods and platinized rods to difference customers.

Our recent and regular supply to USA.

MMO COATED CANTILEVER FOR CATHODIC PROTECTION

MMO COATED CANTILEVER

Vessels, pipelines, pump suction and discharge and condenser box and tanks which are used to store or transport liquids like seawater which is high corrosion nature may not replace time to time. So it should be protected from corrosion on their internal surface by the use of cathodic protection. By passing the DC current through the cantilever which is coated with platinum or MMO (mixed metal oxide) the cathode will be protected and could be monitor by the reference electrodes.

Tianno supplying anodes as per the customer design and as well as our own design cantilever anodes with SS 316, carbon steel and brass enclosures with both MMO Coated and platinized active part. 

Normally Titanium is the noncorrosive nature, but nonconductive material. MMO Coating will give the conductivity in titanium as per the application and amperage. MMO Coated disc used in ship hull protection to avoid high corrosion in seawater. Zinc reference electrode will be placed in particular distance as per the cathodic protection system to monitor the conductivity of the MMO coating disc.

Tianno supplying MMO coating disc for Navy ships as well as abroad clients.

Platinized FRP insulated strip for Cathodic protection of jetty piles and monitored by zinc reference electrodes 

Platinized Titanium anodes take advantage of the low consumption rate and high current density. Voltages in excess of 10 Volts will result in severe pitting of the titanium core causing premature failure. Exterior protection of ships hulls - anodes in the shape of plates, discs or strips

Platinized FRP insulated strip Anode with impressed current leads to protect the hull of the ships. Negative terminal which is connected to ship hull and positive terminal with impressed current anodes.

Underwater steel structures protection like wharves, jetties, sheet pile walls and piers. Usually rod type anodes distributed throughout the structure to be protected to give a good overall protective current distribution.

Change in the potential of an electrode as the result of current flow to or from that electrode. Also, a change in the potential of a corroding metal from its natural steady-state value, as a result of current flow. “Depolarization” is the reverse process of Polarization. Depolarization is sometimes referred to as "hypo polarization”.
