TYPES OF CORROSION FOUND IN THE ELECTRIC POWER INDUSTRY

 


Oxide corrosion
: An electrochemical process on metal surfaces when oxygen molecules dissolve in water. This type of corrosion occurs when lagging isn’t installed properly, or when protective surface coatings fail or were never applied.

Galvanic corrosion: A process that occurs when two dissimilar metals contact each other, creating an electrical reaction that promotes corrosion.

Hot corrosion: Accelerated corrosion due to the presence of salt contaminants that form molten deposits, which damage protective surface oxides.

Erosion: The combination of high fluid surface velocities and an aggressive chemical environment that wears away a surface’s protective scale or coating.

 

PROTECT THE ELECTRIC POWER INDUSTRIES

Corrosion creates significant losses to the electric power industry in generation, transmission, and distribution. Billions of dollars are lost each year due to corrosion-related issues. Maintenance costs rise and profits fall when equipment must be repaired or when spare parts are not ready for immediate use during an outage. A significant percentage of these costs is avoidable with proper prevention measures. Cortec’s capability offers environmentally friendly, highly efficient, and easy-to-use Vapor phase Corrosion Protection for Electric Power Industries applications.

PROTECT THE ENVIRONMENT

Vapor phase Corrosion Inhibitors (VpCIs) offer an environmentally safe method of treatment with low toxicity and low polluting effects. Unlike corrosion inhibiting systems of the past, many of Cortec’s VpCls do not contain chromates or other heavy metals, nitrites, or chlorinated hydrocarbons. With Cortec® VpCls you can turn the tables on corrosion. With the support of our corrosion scientists, engineers, and testing facility, Cortec® can provide simple, environmentally friendly, cost-effective solutions to corrosion problems.

PROTECT CONTINUOUSLY

Unlike conventional methods, such as filming amine corrosion inhibitors, you can inject Cortec® VpCls into any part of your system. Cortec® VpCls go to work immediately and are self-replenishing. Continuous, uninterrupted protection in the liquid phase, interphase, and vapor phase can be added at multiple points. For example, the automatic injection of Cortec® VpCIs into a system — with no attendance operator — provides protection immediately, even on pre-rusted or scaled surfaces.
