Cathodic protection is an electrochemical process which halts the corrosion (natural reaction) of metals in a particular environment, by superimposing an electrochemical cell more powerful than the corrosion cell.
Sacrificial Anodes are fitted or bonded to the metal to be protected which in turn, as it has a greater electrical potential than the anode material, becomes cathodic and causes the anode to sacrifice itself.
In a correctly installed Cathodic Protection System the only corrosion occurs to the sacrificial anode which is replaceable. The number and size of anodes is determined by the type of material and the surface area being protected.
In a simpler explanation we can say that an anode attached to a metal object, such as a boat or underground tank, inhibits the object's corrosion. The anode is electrolytically decomposed while the object remains free of damage.
We can manufacture and supply die cast zinc, aluminum, and magnesium sacrificial anodes which provide low cost cathodic protection of ocean-going vessels, structures and equipment constructed of iron, steel, aluminum, magnesium, and other metals.
We can manufacture different type of anodes, as below, according to the application:
Zinc Alloy (US Mil-A-18001K): For Salt Water Only
Aluminum Alloy (US MIL-A-24779(SH): For Salt & Brackish Water Only
Magnesium Alloy (AZ91D): For Fresh Water Only
Olympic Drive Anodes
Heat Exchanger Anodes
Heater Treater Anodes
Platform Standoff Anodes
Ballast Tank Anodes
Crab Trap Anodes
Our anodes are pressure diecast and manufactured to strict quality standards through an ISO 9001 Quality Management System.
In addition, each alloy is guaranteed to be manufactured to the latest US Military Alloy Specification and is chemically tested regularly in our in-house labs to ensure consistency.
Poorly manufactured anodes may contain high levels of impurities such as iron, which might leave your asset unprotected.
