Question

Give reason:

Metal pipes used for carrying steam have joints in the form of loops.

Answer 1

Metal pipes used for carrying steam have joints in the form of loops.

Reason:

1. A metal pipe expands in all directions when heated.
2. The metal pipes that are used to carry the hot water, steam or other hot liquids have joints in the form of loops.
3. When temperature changes there is expansion and contraction in the pipe accordingly.
4. Due to this expansion and contraction, only the curvature of the loops changes.
5. It saves the metal pipe from damage.

Thus, to avoid the damage to metal pipes due to thermal expansion metal pipes used for carrying steam have joints in the form of loops.
