Why are anti corrosion industrial coatings important?
Protective industrial coatings are a must for metal used in commercial and industrial applications, such as:
steel bridges, pipelines, construction equipment, chemical plants and machinery on manufacturing floors. The two most common
forms of industrial coatings are polyurethane and epoxy coatings.
Utilizing industrial coatings to manage and prevent the corrosion of steel structures is of the utmost importance for both
human and environmental safety. Corroding steel in concrete can weaken buildings and dams. Corroding bridges develop weak
spots and risk collapse. Corroding pipes can crack and leak, contaminating water supplies.
In 2006, corrosion caused a dime-sized leak in a pipe running oil to the Trans-Alaska Pipeline that resulted in about
267-thousand gallons of oil spilling out over the Alaskan tundra
(source: New York Times).
Corrosion not only has adverse effects on safety and the environment, it also has a negative impact on the economy.
According to a 2002 study by the National Association of Corrosion Engineers (NACE International), corrosion prevention in the
U.S. cost an average of $276 billion in 1998
(source: NACE). In the U.S. and other countries
where studies on the costs of corrosion have been carried out, corrosion costs have ranged between 2% to 5% of the gross
national product(source: Corrosion Journal).
Corrosion can take many forms, some of which include:
- Galvanic Corrosion
- Crevice Corrosion
- Stress Cracking
Industrial coatings can help to protect metal from corrosive elements like alkalis, sewage, chemicals, and salts.
