A hydraulic snubber is a mechanical system designed to accommodate the movement of piping systems during thermal expansion. This functionality is crucial in preventing damage to the piping due to temperature fluctuations, as materials typically expand and contract with changes in temperature.

However, it is important to note that while hydraulic snubbers facilitate controlled movement under normal conditions, they impose restrictions on pipe movement when sudden, unexpected loads are applied to the piping system. This is a critical aspect, as the snubber’s primary purpose is to provide stability and mitigate the effects of dynamic forces, which can occur during events such as seismic activity or equipment malfunctions.

In summary, hydraulic snubbers play a vital role in ensuring the integrity and safety of piping systems by balancing the need for movement during thermal expansion with the necessity of restricting motion under unexpected loading conditions.
