Question 1 of 27070

Allowances may be made for the expansion and contraction in piping by the use of expansion joints or __________.

🔍 Key Concepts

• Thermal expansion of piping when carrying hot fluids • How flexibility can be built into a rigid pipe system without using special joints • Common methods used in marine piping to absorb movement and prevent stress on flanges and fittings

💭 Think About

• Which option describes a shape or layout of the pipe itself that can flex slightly, instead of a discrete device or fitting? • If the pipe gets longer when it heats up, which arrangement would allow it to ‘spring’ a bit without breaking or loosening connections? • Think about what you commonly see in long steam or hot-water lines on ships—what do designers add to let the pipe move safely?

✅ Before You Answer

• Eliminate choices that are primarily used for joining or disconnecting sections of pipe rather than absorbing movement. • Identify which choice allows elastic deformation of the piping run itself. • Ask: which option is specifically mentioned in engineering texts as an alternative to expansion joints for handling thermal movement?
