What happens if an obstruction is present in a pipe being heated?

When heating a pipe that has an obstruction, the correct outcome is that it may create a burst when heated. As the temperature rises, the materials in the pipe expand. If there is an obstruction, this can prevent the proper flow of materials or fluids and create points of excessive pressure. The heat will cause the materials of the pipe to expand, and with the added pressure from the obstruction, it can lead to a failure of the pipe, resulting in a burst.

In scenarios where the obstruction restricts the normal flow, the risk of pressure buildup increases significantly. This is particularly critical for pipes that are designed to handle certain conditions and flow rates. A failure due to pressure can lead to serious hazards, such as leaks or bursts, posing safety risks and compromising system integrity. Understanding this principle is vital for anyone involved in heating systems or pipe management.
