API Corrosion and Materials Professional Sample Questions (Q39-Q44):

NEW QUESTION # 39
All piping and equipment exposed to HF acid at any concentration with hardness levels above the recommended limit (237 BHN) are subject to _________.

  • A. Sulfide stress cracking
  • B. None of the above
  • C. Chloride stress cracking
  • D. Hydrogen stress cracking

Answer: D


NEW QUESTION # 40
Ammonium chloride salts are hydroscopic and readily absorb water. A ________ amount of water can lead to very aggressive ammonium chloride corrosion.

  • A. Proper
  • B. Improper
  • C. Large
  • D. Small

Answer: D


NEW QUESTION # 41
Which of the following inspection methods should primarily be used to identify naphthenic acid corrosion (NAC) in a piping system?

  • A. Radiographic testing followed by angle-beam ultrasonic testing
  • B. Radiographic testing followed by ultrasonic measurements
  • C. Angle-beam ultrasonic testing
  • D. Eddy-current testing

Answer: B

Explanation:
API RP 571 on Naphthenic Acid Corrosion (NAC):
"NAC results in thinning, especially in areas of high velocity and turbulence. Standard UT or radiographic inspection followed by UT thickness monitoring is typically used to detect wall loss."
"Advanced techniques like angle-beam or eddy current are not typically required." So, option A correctly reflects the most effective and widely used method.


NEW QUESTION # 42
At a given pressure, the H2S concentration in the sour water _________ as temperature _________.

  • A. Increases, decreases
  • B. Increases, increases
  • C. Decreases, decreases
  • D. Decreases, increases

Answer: D


NEW QUESTION # 43
Carbonate stress corrosion cracking and alkaline stress corrosion cracking are:

  • A. Closely related corrosion mechanisms.
  • B. Different only in the level of alkalinity needed to initiate attack.
  • C. Mechanisms that affect carbon steels and austenitic stainless steels.
  • D. Not preventable by post-fabrication stress relieving of weldments.

Answer: A

Explanation:
In API RP 571, Carbonate SCC and Alkaline SCC are both discussed under mechanisms that occur in basic (high pH) environments, often with similar contributing conditions and prevention methods. The document highlights:
"Carbonate SCC is considered a subcategory of alkaline stress corrosion cracking. It results from the concentration of alkaline carbonates under thermal insulation or deposits."
"Both mechanisms involve the same key parameters: elevated temperatures, tensile stress, and high pH solutions." (Reference: API RP 571, 3rd Edition, Section 4.2.2.4 and 4.2.2.3) Because these mechanisms share similar material susceptibility and operating conditions, they are indeed closely related-option B is therefore the accurate and supported answer.
