Sample API 571 - API 571 Corrosion and Materials Practice Questions

Try these questions from our free API 571 - API 571 Corrosion and Materials practice tests. The correct answer and an explanation follow each question.

  1. API 571-recommended mitigation for wet H2S damage includes which combination of measures?

    • A. Increasing operating temperature to evaporate water and eliminate the wet condition
    • B. PWHT, use of HIC-resistant steel, and process chemical injection (inhibitors/neutralizers)
    • C. Cathodic protection of vessel internals only
    • D. Increasing fluid velocity to prevent H2S concentration

    Answer: B. PWHT, use of HIC-resistant steel, and process chemical injection (inhibitors/neutralizers)

    Wet H2S damage mitigation requires multiple layers: PWHT to reduce residual stress, HIC-resistant steel for susceptible equipment, and chemical injection to reduce H2S content or inhibit hydrogen entry.

  2. What is the primary advantage of Pulsed Eddy Current (PEC) inspection for CUI assessment?

    • A. Detecting surface cracks in stainless steel with high sensitivity
    • B. Measuring average wall thickness through insulation without removing it
    • C. Detecting HTHA internal damage and fissuring
    • D. Measuring weld hardness in carbon steel

    Answer: B. Measuring average wall thickness through insulation without removing it

    PEC can measure average wall thickness through both insulation and coatings, enabling preliminary CUI screening without the costly and time-consuming removal of insulation.

  3. Carbonate cracking in refinery systems is associated with which type of environment?

    • A. Crude oil distillation overhead systems
    • B. Alkaline carbonate/bicarbonate solutions in FCC and amine units
    • C. Amine regenerator overhead at elevated temperature
    • D. Hydrogen reformer effluent streams

    Answer: B. Alkaline carbonate/bicarbonate solutions in FCC and amine units

    Carbonate cracking is an alkaline SCC mechanism affecting carbon steel exposed to carbonate and bicarbonate solutions at elevated temperatures in refinery processes.

  4. Which factor does NOT directly influence the electrochemical corrosion rate of carbon steel in water service?

    • A. Temperature
    • B. pH level
    • C. Water color or turbidity
    • D. Dissolved oxygen content

    Answer: C. Water color or turbidity

    Water color is an aesthetic property and not an electrochemical parameter; temperature, pH, and dissolved oxygen all directly affect corrosion kinetics.
