With steam blanketing, failure occurs as a result of _________ in the tube from the internal steam pressure at the elevated temperature.
A) Stress risers
B) Velocity
C) Hoop stress
D) Tensile strength

Question

Quizplus · Accepted Answer

With steam blanketing, the internal steam pressure at the elevated temperature leads to the accumulation of steam in the tube, creating a hoop stress. This, in turn, causes the metal to weaken and eventually rupture, leading to failure. Stress risers and velocity are not directly related to steam blanketing, and tensile strength does not explain the mechanism of failure in this case.
