  • Pitting Corrosion.
  • Stress Corrosion Cracking.
  • Aqueous Corrosion.
  • However, generally, the selection of the correct corrosion resistant metal to begin with can prevent needing further treatments and prevention methods.

Can corroded water pipes make you sick?

Injecting high levels of microscopic rust may cause iron poisoning, which manifests in fever, headaches, dizziness, low blood pressure, and more.
