The connection between the grounding (earth) system and the cathodic protection system is of paramount importance, especially in the oil and gas industry, marine industries, pipelines, and underground facilities. In today’s world where various industries heavily rely on metal equipment and infrastructure, protecting these assets from corrosion is of utmost importance. One of the most effective methods to prevent metal corrosion is the use of cathodic protection systems. However, for the proper and safe operation of these systems, a proper connection to the grounding system is crucial.
Why is cathodic protection important? Corrosion is a natural process where metals revert to their oxidized forms. In metal pipelines, tanks, and underground or underwater structures, this process can lead to loss of metal thickness, leakage, and significant damage. To combat this problem, cathodic protection (CP) systems are designed to prevent corrosion.
The role of the grounding system in cathodic protection The grounding system acts as a potential reference for the cathodic protection system. A proper connection between the grounding system and cathodic protection offers several advantages:
- Reducing electrical resistance: Connecting the grounding system to the earth reduces system resistance, which helps to reduce unwanted currents and improve the performance of the cathodic protection system.
- Reducing the risk of electric shock: In the event of any electrical fault, the current is safely conducted to the ground, minimizing potential hazards to personnel and equipment.
- Protection against stray currents: In industrial facilities that use a lot of electrical equipment, stray currents can damage metals. Proper grounding can help control these currents.
- Increasing equipment life: By reducing the corrosion rate, the service life of metal equipment is increased and maintenance costs are reduced.
Importance of proper connection To achieve the aforementioned benefits, it is necessary for the connections between the grounding system and cathodic protection to be made with care and according to appropriate standards. Any defects in this connection can lead to a decrease in the efficiency of cathodic protection and consequently, increased corrosion and damage to equipment.
