When condenser tube ends are rolled into both tube sheets, the different rates of material expansion are compensated for by utilizing __________.

🔍 Key Concepts

• Differential thermal expansion between tubes and tube sheets • How rolled tube ends are secured in condensers • Which components are designed to absorb expansion movement versus only improving sealing

💭 Think About

• Which option describes something that allows relative movement between the tube and tube sheet, rather than just making a tighter seal? • In a large condenser, where will most thermal expansion occur: in the tubes, the shell, or a small fitting on the end of the tube? • Which device is typically used specifically to handle expansion of long members, not just to prevent leaks at a joint?

✅ Before You Answer

• Identify which choice actually provides flexibility for movement, not just a static seal. • Consider typical locations of expansion joints in piping and shells—are they usually inside the tube sheet joint or elsewhere? • Ask whether each option is mainly for leak-tightness or for absorbing expansion and contraction over temperature changes.
