3 different ways you can control the corrosion of your asset

Key takeaways

Corrosion is a persistent and costly problem across many industries, from oil and gas to construction and manufacturing. 

Some degree of corrosion is inevitable over time, however, if left unchecked, it can significantly degrade the integrity and lifespan of your assets, leading to unexpected failures and expensive repairs. 

So how do you control the corrosion of your assets? What can you do to keep track of any corrosion? 

This is where corrosion monitoring services become indispensable. 

They provide the expertise and technology needed to track and manage corrosion, ensuring your assets remain in peak condition. 

Let’s explore three effective techniques to control corrosion and reduce its impact on your assets. Have you tried them all?

Understanding corrosion 

Corrosion is a natural process that gradually deteriorates metals through chemical or electrochemical reactions with their environment, such as exposure to moisture, oxygen, salts, and other corrosive substances. 

This degradation can 

  • compromise the structural integrity and functionality of assets, 
  • …leading to potential failures
  • …leading to costly repairs. 

Factors like environmental conditions, material properties, and protective measures influence the rate and extent of corrosion. 

Understanding and managing corrosion is essential for maintaining the longevity and safety of structures and equipment across various industries.

Controlling corrosion 

Let’s find out more about some of the techniques available to control corrosion. 

1. Cathodic protection

Cathodic protection (CP) is one of the most effective methods for preventing corrosion, particularly for underground or submerged structures like pipelines, tanks, and ships. 

This technique involves making the metal surface the cathode of an electrochemical cell. Essentially, CP supplies an electrical current to the metal surface, countering the corrosion process.

Why use cathodic protection?

Prolongs Asset Life: By preventing the metal from corroding, CP significantly extends the life of structures.

Cost-Effective: Over time, the investment in CP can save substantial amounts of money by avoiding costly repairs and replacements.

Versatility: It can be applied to various environments, including soil and water, making it a versatile option for different industries.

Corrosion monitoring services are crucial here as they help in designing, installing, and maintaining cathodic protection systems. 

Regular monitoring ensures that the CP system remains effective and adjustments are made as necessary to maintain optimal performance.

2. Coating and linings

Applying protective coatings and linings to metal surfaces is another highly effective corrosion control method. 

These coatings act as a barrier, preventing corrosive substances from reaching the metal surface. Common types include epoxy, polyurethane, and zinc coatings.

Why use coatings and linings?

Barrier Protection: They provide a physical barrier between the metal and the environment, preventing moisture and other corrosive agents from initiating the corrosion process.

Customisable: Coatings can be tailored to specific environmental conditions and asset requirements.

Ease of Application: They can be applied to new or existing structures with relative ease.

The effectiveness of coatings and linings depends on their proper application and maintenance, which is where our corrosion monitoring services play a critical role. 

These services ensure that the coatings are applied correctly and are regularly inspected for signs of wear or damage. Early detection through monitoring can prevent minor issues from becoming major problems.

3. Corrosion inhibitors

Corrosion inhibitors are chemicals that, when added to a corrosive environment, decrease the rate of metal oxidation. 

These inhibitors are particularly useful in closed systems like boilers, cooling towers, and pipelines where they can be introduced into the fluid medium.

Why use corrosion inhibitors?

Effective in Various Systems: They can be used in different types of systems, making them a flexible option for many industries.

Minimal Downtime: Introducing inhibitors into the system often requires minimal disruption to operations.

Cost-Effective: They provide a relatively low-cost solution to manage corrosion, especially in complex systems where other methods might be impractical.

How to identify areas of corrosion

Corrosion mapping is a highly effective method for inspecting assets to pinpoint areas of concern.

Promptly addressing and repairing these identified areas extends the lifespan of components, ultimately resulting in long-term savings on operational costs.
