  1. The removal of surface material by impacting materials is called:
    Erosion
  2. The removal of a material's protective scale by impacting materials is called:
    Erosion-corrosion
  3. Which of the following is not a primary factor contributing to Erosion?
    A) Corrosiveness of the environment
    B) Velocity of impacting particles
    C) Density of impacting particles
    D) Size of impacting particles
    E) Impact angle(angle that impacting particles strike metal)
    A) Corrosiveness of the environment
    (this multiple choice question has been scrambled)
  4. Which of the following is not a primary factor contributing to Erosion-Corrosion?
    A) Impact angle( angle that impacting particles strike metal)
    B) Corrosiveness of the environment
    C) Tensile strength of the metal
    D) Velocity of impacting particles
    C) Tensile strength of the metal
    (this multiple choice question has been scrambled)
  5. A prime location for Erosion is:
    in Catalyst piping
  6. In the Crude Unit, piping and vessels may have high metal loss from Erosion-Corrosion if the unit is exposed to:
    naphthenic acid
  7. Erosion or Erosion-Corrosion usually appears as:
    directional pits, grooves, or waves
  8. A 6 NPS Carbon steel line is experiencing Erosion-Corrosion. A reasonable solution would be to:
    increase the line size to 10 NPS
