Corrosion Mitigation & Life Extension for Steel Transmission Structures

Corrosion Mitigation Defined

Corrosion mitigation refers to the set of techniques and strategies utilized to protect steel structures, either transmission or distribution assets, from the destructive effects of corrosion in various environments. Corrosion is a natural process in which steel deteriorates due to reactions with its surroundings, especially in the presence of water and corrosive agents. This can impact industrial structures, assets, and equipment, leading to compromised structural integrity and increased maintenance costs.

Different Corrosion Types

Some types of steel corrosion include:

  1. Uniform: A metal surface corrodes evenly due to exposure to corrosive agents.
  2. Galvanic: This involves mixed metals, where the anode metal sees a rapid corrosion rate and the other has cathodic protection.
  3. Pitting: Chloride or acidic environments create small, deep holes on the metal surface.
  4. Crevice: Moisture accumulates in gaps between metal surfaces.
  5. Intergranular: This typically occurs due to improper welding or heat treatment processes.
  6. Stress Cracking: Marine environments or chemical processing industries cause tensile stress and sudden failure of the metal.

Understanding the different types of steel corrosion helps select appropriate corrosion mitigation strategies.

How Osmose Can Help with Your Corrosion Mitigation Needs

Osmose has decades of experience working in unique and challenging environments. We can quickly identify the most effective coating solution for all your corrosion needs. Contact us to learn more.

Protective Coatings

Specialized coatings are applied to mitigate corrosion and extend the useful service life of your steel structures. Osmose works with utilities to understand the challenges within their footprint. These challenges include issues attributed to weather, salt spray, low soil resistivity, or industrial pollutants. 

With decades of experience behind us working in unique and challenging environments, Osmose can identify the most effective coating solution relative to each specific environment.
