Cathodic protection is the most common electrochemical technique used to prevent corrosion on pipelines, storage tanks, ship hulls, underground tanks etc. The process occurs when a DC current is passed through an anode and cathode so that the metal becomes cathodic and prevents corrosion.

Cathodic protection is one of the main technique to prevent corrosion. Cathodic protection is of two types they are Impressed Current Cathodic Protection (ICCP) and Galvanic Protection also known as DCCP. Cathodic protection systems protects a wide range of metallic structures in various environments. Titanium tubular anodes are manufactured using titanium seamless tube and coated with platinum group precious metal mixed oxide coating.

Titanium tubular string for pipelines are arranged in ground beds either distributed or in a deep vertical hole depending on several design and field condition factors including current distribution requirements.

Ships are often exposed to very harsh marine environments. Due to the environment in which they operate, the ship’s hull is often exposed sea environmental corrosion that can reduce the life.

The corrosion of seawater as regards to general corrosion on steel increases with increasing temperature, oxygen content, water velocity, the content of corrosive contaminants, eroding particles, and conductivity. The seawater containing salt forms a perfect electrolyte with the ship’s hull, fully made up of iron (mild steel), to form a galvanic cell.

Galvanic cell occurs when two dissimilar are in contact with each other leads to corrosive medium (electrolyte) i.e. the more active metal undergoes corrosion and the less active metal acts as a cathode and stays protected. Like that way, people use to paint the ship hull. But it is impossible to paint often, since it can done only in dry dock condition.

So that people go for depressed current cathodic protection system with sacrificial anodes like aluminum, zinc, magnesium and GI anodes. But we should replace the anodes in very short period. 

Impressed current cathodic protection with MMO Coated and Platinum plated Titanium and Niobium anodes will last longer for 15 to 20 years and reference electrode for monitoring the system.

In addition to being made of solid titanium wire is coated with a thin layer of iridium and tantalum oxide, MMO wire anodes also have a low consumption rate and maintain a nearly constant voltage throughout their service lives. MMO wire anode is distinguished by its low consumption rate and ease of installation. It is used in the majority of cathodic protection applications. Ti Anode fabricators Pvt Ltd has three decades of experience in manufacturing ICCP anodes for more details visit our website: http://www.cpanode.com/ or our Facebook page: https://www.facebook.com/pg/Tiaano-ICCP-Anodes-125008582229120/posts/

The following are some of the advantages of the ICCP system:

Impressed Cathodic Protection System has several advantages over other types of cathodic protection systems because it makes use of an external power supply to power both the anode and cathode systems, making it possible to protect any structure, regardless of its size.

When compared to other prevention methods available on the market, the use of ICCP systems has a longer life span and greater durability.

The structure's life expectancy has been extended.

The anodes are small and lightweight, making them simple to install and store.

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.  

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.

Anodes for ICCP systems are available in a variety of shapes and sizes in different application. These consist of anodes connected to a DC power source, often a transformer-rectifier connected to AC power. In the absence of an AC supply, alternative power sources may be used, such as solar panels, wind power or gas powered thermoelectric generators.

Common anodes are tubular and solid rod shapes or continuous ribbons, mesh of various materials. These anodes are made from Titanium, niobium with mixed metal oxide, platinum coated.

For pipelines, anodes are arranged in ground beds either distributed or in a deep vertical hole depending on several design and field condition factors including current distribution requirements.
