Impressed Current Cathodic Protection (ICCP) Anodes

MMO Coated / Platinized Titanium & Niobium Anodes

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by passing positive connection in the anodes side and negative connection in the cathodes side.

Platinized cantilever anode is used for protecting pipeline internals, suction and condenser box internal for 30 years and more by applying DC current from rectifier. Cantilever anode is coated with platinum or MMO (mixed metal oxide). The cathode will be protected and could be monitor by the reference electrodes.

Platinized titanium rods are usually used in cantilever anode. 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 of Platinum coating:

•          Low consumption rate that conserves precious platinum.

•          Corrosion resistance ensures durability with easy maintainability.

•          Light weight, as well as favorable current distribution in electroplating.

•          Favorable dimensional stability.

Manufacturing and Supply of Platinized Titanium Rod Anode for Cathodic Protection

What is Cathodic Protection?

Cathodic protection system is to protect a wide range of metallic structures in various environments. Common applications or environment to protect steel, water or fuel pipelines and steel storage tanks such as huge oil tanks, chemical storage tanks, steel pier piles, ship and boat hulls, offshore oil platforms and onshore oil well casings and metal reinforcement bars in concrete buildings and structures. Corrosion can be defined as degradation of metal by forming electrical circuit where electrons get exchanged.

Ti Anode Fabricators Pvt. Ltd,Chennai, India is one of the best manufacturer in making MMO anodes or mixed metal oxide Cathodic Protection anodes and reference electrodes for a full range of cathodic protection application, by using Impressed Current Cathodic Protection (ICCP) process. The principle of cathodic protection is to connect an external anode to the metal and passing an electrical DC current so that all areas of the metal surface become cathodic and therefore do not corrode.

The external anode is to be an impressed current cathodic protection anode, where the current is impressed from an external DC power source. DC current is sent through an insulated wire to the anodes [which are either Dimensionally stable anodes / dimensionally stable anodes - MMO coated titanium anodes, Platinised titanium anodes, Platinized niobium anodes or their copper cored with platinum plated surface] buried in the soil like underground storage tank, pipeline, ship hulls etc.

Platinised Titanium Anode:

A platinized titanium anode is simply a titanium anode coated with platinum. These anodes act as an inert anodes and are non-consumable and long lasting. These anodes are insoluble in electrolyte where electrolysis is present. Platinized Titanium Rod are usually used in cantilever anode which is used for protecting pipeline internal, pump internal & condenser box internal for 30 years and more by applying DC current with transformer rectifier. 

Platinised CP Rod

Applications:

  • Deep & conventional ground beds.
  • Jetties in fresh, brackish and salt-water electrolytes.
  • Water tanks.
  • Lock Gates.
  • Intake Screens.
  • Marine application.

Tiaano’s different types of anodes for Cathodic Protection:

Platinum plating and MMO coating have long life in all environments and services and also withstand in natural waters. Tiaano design and manufacture various types of anodes such as:

  • Strip/Disc Anode
  • Ribbon mesh anode
  • Tubular String Anode
  • Canister/Cantilever anodes
  • Piggy back anodes
  • Cables etc.

We also supply anodes for electroplating, electrolysis, water treatment deionization and various applications.

MMO COATED TITANIUM/NIOBIUM RUBBERIZED DISC ANODE AND ZINC REFERENCE ELECTRODE FOR CATHODIC PRODUCTION USED TO PROTECT THE SHIP HULL FROM SEA WATER CORROSION

clock May 13, 2021 11:53 by author admin

MMO (Mixed Metal Oxide) coated rubberized disc anodes are used to protect the ship or hull from sea water corrosion. Normally Titanium having noncorrosive, but it contains nonconductive material. MMO coated will give the conductivity in titanium as per the application and amperage. Zinc reference electrode will be placed in particular distance as per the cathodic protection system to monitor the conductivity of the MMO coating disc.   

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 (mid steel) which made of oxidation.

When using MMO coated rubberized disc anode to protect the ship hull from sea water corrosion, external current are applied to convert high-potential anodic sites on a ship hulls to low-potential cathodic sites. This ensures the ship hull surface is protected from corrosion.

We can install MMO coated disc in the hull by passing DC current by a rectifier which will protect the ships life longer nearly 20 to 25 years depends upon the usage of the ship which afloat often.  

MMO coated rubberized disc size well be customized depends upon the design of the CP system.

Advantages:

  • Ø  Durability compared to galvanic anode.
  • Ø  Demonstrate reliability.
  • Ø  Optimum documented corrosion production at minimum overall cost.  
  • Ø  Anodes are lite, sturdy and compact for easy shipping, storage and installation.

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.

MMO COATED CANTILEVER & REFERENCE ELECTRODE FOR CATHODIC PROTECTION

MMO COATED CANTILEVER & REFERENCE ELECTRODE

MMO COATED CANTILEVER

Vessels, pipelines, condenser box and tanks which are used to store or transport liquids can also be protected from corrosion on their internal surfaces 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.

Tiaano supplying anodes as per the customer design and as well as our own design.

REFERENCE ELECTRODE

A reference electrode must have specific electrical, physical and chemical properties. It must facilitate the measurement of accurate pipe/soil/reference electrode potentials on pipelines. It must ideally have a stability that is sustainable for years. For this to occur it should not be polarized by the very low electrical current that will flow in a measurement circuit. The potential should be measured with a high impedance multi-meter or voltmeter.

Reference electrode allows you to measure the potential of the working electrode without passing current through it while counter (auxiliary) electrode allows you to pass current. If oxidation occurs at the working electrode, reduction using the same magnitude of current is sustained at the counter electrode and hence there is no current flow between working and reference electrode(high input impedance) enabling us to follow changes in working electrode potential accurately. This is not possible in a two electrode system although we can get crude values by using certain types of electrodes which can act simultaneously as working and reference electrode.

Tiaano supplying reference electrodes like zinc, AgAgcl for the pipeline, jetty etc.,
