Corrosion Resistance

What Does Corrosion Resistance Mean?

Corrosion resistance is defined as the ability of a material (metallic or non-metallic) to withstand corrosion damage caused by oxidation or other chemical reactions. Resistance to corrosion can be achieved either through the intrinsic resistant properties of the material or by using corrosion resistant products such as paints, coatings or corrosion inhibitors.


Trenchlesspedia Explains Corrosion Resistance

Corrosion resistance (like corrosion rate) is an important factor in determining the serviceable life-span and maintenance schedule of sewer pipelines. Typically, steel and reinforced concrete by themselves are not very resistant to corrosion caused by the sulfuric acid gasses produced by bacteria in sewer pipelines and require regular inspection and maintenance.

Piping materials that are known to be resistant to microbiological corrosion are High-density polyethylene (HDPE), polyvinyl chloride (PVC) and Acrylonitrile butadiene styrene (ABS) pipes. Trenchless rehabilitation methods such as Cured-in-Place (CIPP) lining are corrosion resistant and help to increase the longevity sewer pipes.
