API 571 - Erosion corrosion Practice Test Questions And Answers 100% Pass.

Erosion - correct answers The removal of surface material by impacting materials is called : Erosion - Corrosion - correct answers The removal of a material's protective scale by impacting materials is called : Corrosiveness of the process - correct answers Which of the following is not a primary factor contributing to Erosion ? Particles in the process wear away the scale / corrosion on the equipment , exposing bare metal to the corrosion environment . The equipment " recorrodes " and that scale continues to be removed . - correct answers best describes the Erosion - Corrosion process ? The soundness of the metal - correct answers Which of the following is not a primary factor contributing to Erosion - Corrosion ? often much higher than the normal corrosion rate from the process . - correct answers The Corrosion Rate resulting from Erosion - Corrosion is : high velocity rates, liquid droplets entrained in a flowing gas ,Solid particles in a flowing liquid . - correct answers Sometime Erosion - Corrosion is caused by : The corrosion rate will probably increase due to increased process velocity . - correct answers A 6 NPS Sch 40 CS piping system has failed after 10 years due to Erosion - Corrosion . The line is replaced with a 6 NPS Sch 160 CS pipe . Which of the following is true ? in catalyst piping . - correct answers A prime location for Erosion is : naphthenic ac id . - correct answers In the Crude Unit , piping and vessels may have high metal loss from Erosion - Corrosion if the unit is exposed to : directional pits , grooves or waves . - correct answers Erosion or Erosion - Corrosion usually appears as : Inside corrosion is likely on the bottom of the pipe ( 6 o'clock position ) . to 10 replace lowering - correct answers pipe in liquid service that also contains some particles The velocity in the pipe is relatively low about 5 ft / second . Which of the following describes the potential for Erosion or Erosion / Corrosion ? increase the line size to 10 NPS - correct answers A 6 NPS carbon steel line is experiencing Erosion - Corrosion . A reasonable solution would be to : Random UT - correct answers Which of the following is not a good NDE technique for finding corrosion from Erosion or Erosion - Corrosion ? Infrared Thermography - correct answers While the equipment is in operation , which of the following NDE techniques is a good for finding refractory degradation ? 13 mpy - correct answers is the expected corrosion rate from Erosion - Corrosion ? A carbon steel pipe is filled with seawater flowing at 4 fps ( feet - per - second ) . What
