What is Corrosion?
Corrosion is a naturally occurring phenomenon that affects everyone’s life on a daily basis.
Where is Corrosion?
In many instances, corrosion is readily obvious, the rusty bridge that needs repainting or the corrosion blister under the paint of your car. In others, the defect is hidden, your water heater which was fine suddenly develops a leak while you’re away on vacation.
Cost of Corrosion
The cost of controlling corrosion and the costs associated with the damage it causes is substantial. In 2002, NACE International (National Association of Corrosion Engineers) and the US Federal Highway Administration published the results of a two year study on the costs of corrosion. The study Corrosion Costs and Preventive Strategies in the United States estimated the direct cost of corrosion was $276 billion, approximately 3.1% of the nation’s Gross Domestic Product.
In 2013, G2MT Laboratories published a new study that estimated the cost of corrosion exceeded $1 trillion.
G2MT Laboratories states that, “At over 6.2% of GDP, corrosion is one of the largest single expenses in the US economy yet it rarely receives the attention it requires.”
Direct and Indirect Costs Associated with Corrosion
The direct costs associated with corrosion are:
- Excessive maintenance/repair/replacement
- Loss of product/process downtime
- Product contamination
- Excessive materials and energy (oversized equipment)
- Environmental clean-up and fines
There are also indirect costs such as: loss of consumer confidence, poor appearance, increased regulation, and safety.
Corrosion Mitigation Methods
The most commonly used methods to mitigate corrosion includes: design, coatings, corrosion resistant alloys and polymers, corrosion inhibitors and cathodic protection. The use of appropriate corrosion protection and control methods can prevent damage to property and the environment, protect public safety and the environment, thereby saving billions of dollars.
Maintenance for Corrosion Protection
Maintenance is an especially challenging area. Insufficient attention is often paid to the long term requirements of an asset once construction has been completed. This is best illustrated by large infrastructure projects like bridges, roadways, pipelines (gas and oil) and drinking water and sewage systems. Much of this infrastructure is reaching its design life and resources need to be committed to maintaining and extending the life of these valuable assets.
Education, training and the exchange of ideas are key factors to promote greater corrosion awareness. As Neil Young explained in his 1979 album, “Rust Never Sleeps”.
