Test Your Sewer IQ – Understanding Underground Pipeline Corrosion

What do you know about underground pipeline corrosion? Keep reading to learn about the different types of corrosion, then test your Sewer IQ with this quick quiz from Envirosight!

Erosion is the most common cause of corrosion, and it is also the easiest to understand. When corrosive liquids flow along sewer lines, the material wears away, leaving gullies, grooves and general flow patterns. Erosion can also cause a failure faster than any other type of corrosion.

Uniform attacks occur when an electrochemical or chemical reaction thins pipe material. It’s easy to measure this type of corrosion using simple chemical tests.

Galvanic corrosion happens when two different types of metals react upon meeting and corrode when immersed in conductive or corrosive liquid. The metal that is less resistant to corrosion starts to degrade faster than it normally would.

Pitting is a type of corrosion that occurs when small holes or divots form in pipe walls. This can be tougher to spot because holes may just look like rough sidewall when clustered together, and they can be covered with corrosion products and debris.

The better you understand these different types of corrosion and erosion, the faster you can remedy problems and prevent major issues from occurring. To troubleshoot areas in drain pipes and laterals, we highly recommend the Envirosight Verisight Pro+. By pairing smart technology with a rugged push camera, the Verisight Pro+ lets you capture detailed footage in even the harshest conditions, and the unique spring makes it easy to navigate through tees and bends.
