Expansion loops are typically used on which type of installations?

Expansion loops are commonly utilized in pipe installations that involve long runs of piping systems, particularly in industrial settings like chemical plants, power plants, and other facilities where temperature changes can cause significant thermal expansion or contraction of the pipes. The function of expansion loops is to absorb the stresses that arise from these temperature variations, which can lead to bending and deformation of the piping if not adequately managed.

In the context of long runs of pipe, these loops provide a flexible section that can accommodate movement without damaging the entire system. This is crucial in preventing leaks and ensuring the integrity of the piping system. Long pipe runs are more susceptible to the effects of thermal expansion due to their length and the materials typically used, which have different rates of expansion and contraction.

Short runs of pipe generally do not require expansion loops since the movements are minimal and can be accommodated without such structures. Underwater installations and residential plumbing often have different requirements and stressors that do not necessitate the use of expansion loops in the same way as industrial piping systems.
