Questions and Answers

What is the safest form of transportation in the United States according to the US Department of Transportation?

  • Natural gas transmission pipelines (correct)
  • Air transportation
  • Water transportation
  • Road transportation

What is corrosion?

  • Nature's slow reaction to metal which causes it to rust and deteriorate over time (correct)
  • A supplemental process called cathodic protection
  • A state-of-the-art coating formulation
  • A power supply inducing a low voltage DC charge through the ground beds and into the soil

What is the purpose of fusion bonded epoxy (FBE) coating?

  • To act as a corrosion-resistant coating (correct)
  • To deteriorate the anodes instead of the pipeline
  • To stop the electrical current flow from the pipe to the surrounding soil
  • To induce a low voltage DC charge through the ground beds and into the soil
