Cathodic Protection Services

Our Cathodic Protection System is a proven and reliable method of achieving corrosion control in industrial metals. Corrosion happens to be a progressively destructive process, which is initially challenging to identify until it has advanced. In most cases, corrosion is often identified when it is too late. Identifying corrosion in submerged or buried equipment or structures can be even more challenging, which makes Cathodic Protection (CP) so important.

Often working in conjunction with protective coatings or vapor phase corrosion inhibitors (VpCI), the Cathodic Protection system design is a provable and highly reliable way of controlling and even minimizing corrosion. The method was initially developed to be used in the shipping industry, but today it is used across a multitude of industries where safety, protection, and the long-life of the structure is paramount, namely in the oil & gas, power generation, and petrochemical industry.

What is Cathodic Protection?

Developed around 200 years ago, cathodic protection is a special electrochemical process that prevents anodic reaction of metal dissolution on the surface’s structure. Metal mined from ores, and refined continue to have a natural bias and will slowly return to their oxidized state, especially when in the presence of oxygen and water. Take, for instance, the fact that iron ore is similar to the composition of rust on steel pipes. The process is called corrosion. That change from a refined metal like steel into its oxidized state, i.e., rust occurs as ‘Anodic’ reaction on the metal’s ‘Anode.’

M           →           M+          +            e

(Metal)                 (Metal Salt)        (Electron)

The reaction will create free electrons, which then pass through the metal itself to yet another location on the surface referred to as the ‘Cathode.’ Here’s where what’s called the ‘Cathodic’ reaction takes place generally in an acidic environment.

2H+                        +             2e          →           H2

(Hydrogen Ions)                (Electrons)           (Hydrogen Gas)

So, corrosion takes place at the anode, with the metal consumed over some time, but there is no corrosion at the cathode. So, the concept behind cathodic protection is to change the entire structure into a ‘Cathode’ by removing the ‘Anode,’ i.e., corrosion locations to someplace where they can be easily protected and controlled.
