Which pipe support device uses springs to accommodate thermal expansion?

The variable spring hanger is designed specifically to accommodate thermal expansion and contraction in piping systems. As temperatures within the pipes fluctuate, they expand or contract, creating forces that can place stress on the system if not managed properly. The variable spring hanger utilizes a spring mechanism that can compress or extend in response to these changes, effectively managing the movements caused by thermal effects. This capability allows the hanger to provide both support and flexibility, ensuring that pipes remain properly aligned while preventing undue stress on the joints and connections.

Other types of supports, such as fixed supports, cantilever supports, and adjustable supports, do not possess the same functionality. Fixed supports fully restrict movement and do not permit any flexibility, which can lead to damage in the face of thermal expansion. Cantilever supports typically offer stable support for pipes extending horizontally, but they also lack the ability to adjust for thermal movements. Adjustable supports, while they can be modified to some extent, do not have the inherent spring mechanism that allows for self-adjustment in response to temperature changes. Therefore, the variable spring hanger is the optimal choice for managing thermal expansion in piping systems.
