________ has been a major problem on coke drum shells.
A) Thermal fatigue
B) Stress cracking
C) Erosion
D) Temper embrittlement

Question

Quizplus · Accepted Answer

Coke drum shells are subjected to extreme temperatures during the coke production process, which can cause thermal cycling and lead to thermal fatigue failure. This is a major problem in coke drum operations. Stress cracking, erosion, and temper embrittlement are also potential issues in coke drum shells, but thermal fatigue is the most commonly observed failure mechanism.
