What is the main purpose of a pipe hanger?

The main purpose of a pipe hanger is to provide support and stability to the piping system. Pipe hangers are essential components that secure pipes in place within a plumbing or piping system, ensuring that they are held in a fixed position. This stability is crucial to maintain the alignment of the pipes, which helps in preventing stress on joints and connections that could lead to leaks or failures over time.

While it is true that some hangers may also accommodate minor movement due to thermal expansion, their primary design and function focus on the structural support of the piping system. Other functions, such as isolating vibration or connecting pieces of pipe, might be achieved through different devices or accessories, but the core role of hangers is to stabilize and support the pipes to maintain the integrity and efficiency of the system.
