🔍 Key Concepts

• Thermal expansion and how machinery foundations handle it • How large turbine casings are supported so they can grow in length when heated • Difference between piping expansion devices (loops, corrugations) and base/foundation arrangements for main machinery

💭 Think About

• Think about what part of the turbine actually changes length when it heats up, and in which direction that growth mainly occurs. • Consider whether the solution should allow the casing to move, the piping to move, or both—and which one the question is specifically asking about. • Ask yourself which option describes a way of supporting the turbine so that one end can move freely as it expands while the other end stays fixed.

✅ Before You Answer

• Verify which options refer to piping arrangements versus turbine support/foundation arrangements. • Check which choice allows longitudinal movement of the casing rather than just flexibility in a line or fitting. • Confirm that the selected option would prevent thermal stress and distortion in the turbine casing, not just in the steam lines.
