← ScienceWhich outcome occurs when thermal expansion loop in a steam distribution cycle fails to maintain designed curvature?
A)Pipe rupture from excessive axial stress✓
B)Turbine blade erosion from steam pressure
C)Condensate backflow into the steam generator
D)Control valve oscillations causing pressure surges
💡 Explanation
When a thermal expansion loop loses its curvature, its ability to absorb thermal expansion decreases because material yielding, resulting in high axial stress on adjacent pipe sections upon heating, possibly exceeding the pipe's tensile strength. Therefore pipe rupture results, rather than blade erosion, backflow, or control valve problems rooted from different origins.
