Cathodic Protection Services
Cathodic Protection is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode in the same cell.
The steel pipeline is cathodically protected by its connection to a sacrificial magnesium anode buried in the same soil electrolyte.
Cathodic protection was first developed by Sir Humphrey Davy in 1824 as a means of controlling corrosion on British naval ships.
Cathodic protection prevents corrosion by converting all of the anodic (active) sites on the metal surface to cathodic (passive) sites by supplying electrical current (or free electrons) from an alternate source. Usually this takes the form of galvanic anodes, which are more active than steel.
Cathodic Protection Systems
Cathodic protection systems are systems which are designed to control the corrosion of a metal surface. Corrosion can destroy the integrity of your infrastructure. Patching the damaged area may seem the simplest and least expensive process of repair, but it may also be the least effective method for cathodic protection. Materials used for patching soon require repairs, and on a cyclical basis – each time growing more expensive.
These repairs weaken the structure and may lead to the need for total replacement.
Our engineers understand the principles of corrosion, we can provide you with a cost effective corrosion control system designed to protect your infrastructure and prevent corrosion in new structures and mitigate corrosion in existing structures .
