최신 ICP Programs API-571 무료샘플문제 (Q120-Q125):

질문 # 120
Differential expansion in bimetallic welds can give rise to:

정답：C

설명：
API RP 571 under Thermal Fatigue highlights:
"Differential thermal expansion between dissimilar materials (e.g., carbon steel and stainless steel) in welds causes high cyclic stresses that can result in thermal fatigue cracking."
"These stresses typically occur during transient thermal cycling such as startup/shutdown operations." (Reference: API RP 571, Section 4.2.1.5 - Thermal Fatigue) Thus, the correct mechanism resulting from differential expansion in bimetallic welds is thermal fatigue, making option B correct.


질문 # 121
Cracking of dissimilar weld metals occurs on the _________ side of a weld between an austenitic and a Ferritic material operating at high temperatures.

정답：A


질문 # 122
With sulfuric acid corrosion, carbon steel corrosion rates increase significantly if the flow velocity exceeds about ________m fps or at acid concentrations below _________.

정답：B


질문 # 123
Naphthenic acid corrosion (NAC) is most severe in what phase of flow?

정답：C

설명：
API RP 571 on Naphthenic Acid Corrosion (NAC) details:
"NAC is most aggressive in two-phase flow where the shear stress is high, such as in elbows, reducers, and at orifices."
"High velocity and turbulence in two-phase flow strip protective layers and accelerate corrosion." Therefore, option A is the correct and most critical phase.


질문 # 124
A 5Cr-1Mo piping system in the hydrogen unit shows significant internal wall loss after 2 years in service due to CO² corrosion. Which material would be best suited to use to install a new pipe system?

정답：D


질문 # 125
......
