Impressed Current Anodes

For larger structures, or where electrolyte resistivity is high, galvanic anodes cannot economically deliver enough current to provide protection. In these cases, impressed current cathodic protection (ICCP) systems are used. These consist of anodes connected to a DC power source, often a transformer-rectifier connected to AC power. Anodes for ICCP systems are available in a variety of shapes and sizes. Common anodes are tubular and solid rod shapes or continuous ribbons or wires of various materials.

 High silicon cast iron anode

Mixed Metal Oxide Tubular Anodes

Rod type silicon cast iron anodes are probably the most common anodes used in ground bed construction and the high corrosion resistance environment.

 

 APPLICATION

Vertical Ground beds, Horizontal Ground beds, Distributed Anodes and Deep well Ground beds.

Suitable For Use in Soils, Mud, Carbonaceous & Petroleum Coke Backfill.

MMO Anodes are manufactured using titanium, which has been coated with Mixed Metal Oxide coating.

This permits greater current output in all types of ICCP anodes and provides the longest life.

 

APPLICATION

Marine Structures, Seawater Intakes, Deep-well Ground-beds, Horizontal Ground-beds, Distributed Anodes, Tank Internals ,Suitable For Use In Soils, Mud, Carbonaceous & Petroleum Coke Backfill; Fresh, Brackish and Sea Water.

MMO Ribbon Anode

MMO Wire node

PETUNIA ribbon anodes for Use in under tank and Reinforced concrete structures are manufactured using titanium substrate, which has been coated with Mixed Metal Oxide coating.

The ribbon mesh anode is field assembled with titanium conductor bars and a resistance welder.  The design life of the anode varies with operating current.

 

APPLICATION :

Reinforced Concrete Structures & Above Ground Storage Tank Bottoms

MMO Wire Anode consists of solid titanium wire which meets that been coated has with Mixed Metal Oxide.

PETUNIA wire anodes are manufactured in two diameters: 1.5 mm and 3.0 mm.

PETUNIA wire anodes can be used in a wide variety of cathodic protection applications

APPLICATION:

Tank Internals, Continuous Horizontal Ground beds, Discontinuous Horizontal Ground beds.

MMO Mesh Anode

PETUNIA mesh anodes are manufactured using titanium substrate, which has been coated with Mixed Metal Oxide coating.

 

Diffusion of chloride ions into the concrete leads the corrosion of steel rebars. The best way to prevent armatures corrosion is cathodic protection.

The Anode Mesh is used in the Cathodic Protection of Reinforced Concrete Structures

APPLICATION:

Bridges, Decks, Harbours, Cooling Towers and Other Concrete Structure

Piggyback Wire Anode Systems

For use on pipelines, the product comprises Mixed Metal Oxide Wire Anode material “piggybacked” to a cable at predetermined intervals (to aid current distribution and attenuation). The wire and cable is contained within a cotton sock filled with calcined petroleum coke breeze backfill. The Piggyback Sock Anode is placed alongside the pipeline with suitable lengths of cable at each end of the loop allowed for termination into a junction box.

CANISTERED ANODES

Canisters are pre-packed anodes. anodes are installed in a spirally wound galvanized steel canister. The canister is packed firmly with metallurgical coke or calcined petroleum coke to ensure even current transfer from the anode.

Sacrificial Anodes

 Aluminium Anodes

Zinc Anodes

Aluminium alloy anodes have been formulated primarily for use in seawater. Alloys are also capable of achieving high output capacity in mud and brackish water of resistivity up to 150 Ohm cm. Aluminium anodes have approximately three times the capacity of zinc alloys.

Typical  applications include:

• harbours

• jetties

• platforms

• ship hulls

• ballast tanks

• drill rigs

• pipelines

• offshore windmill parks

• Tank Internals

Zinc generally used as a sacrificial anode material in seawater. Zinc anodes used for Cathodic Protection are cast from high purity zinc (99.99%) alloyed with aluminium and cadmium with limitations on the level of lead, iron and copper.

Typical applications include:

 Submarine pipelines, ballast tanks, offshore structures, storage tank internals, quay walls, water tanks, marine applications and ships hulls.

Magnesium Anodes

Magnesium anodes are suitable for temporary protection of buried pipelines, protection of well coated buried pipelines, internal protection of water tanks, and “Hot spot” locations for buried steel structures and also suitable for use in soils, fresh water.
