Which two methods are commonly used to manage pipe expansion or contraction?

Expansion loops and offsets, as well as expansion joints, are widely recognized methods used to manage the expansion and contraction of pipes due to temperature changes. When fluids flow through pipes, the temperature variations cause the material to expand when heated and contract when cooled. If not properly managed, this thermal movement can lead to stress, damage, or leaks in the piping system.

Expansion loops are designed to create a loop in the piping, allowing for flexibility and movement as the pipe expands or contracts. This design can effectively accommodate changes in length without subjecting the piping system to excessive stress. Similarly, expansion joints are components that can absorb movements and allow for the thermal expansion and contraction of the pipes, maintaining the integrity and functionality of the system.

Both of these methods are critical in ensuring the longevity and reliability of piping systems across various applications, making them the preferred solutions in managing thermal movements.
