What is the role of a pipe hanger?

The role of a pipe hanger is fundamentally to support and secure piping in place. Pipe hangers are critical components in piping systems, as they are designed to hold pipes at the correct elevation and alignment, ensuring that the entire system operates safely and effectively. By providing this support, pipe hangers prevent excessive stress on joints and connections, which can lead to leaks or breaks over time due to movement or vibrations.

Additionally, having the correct support system in place is essential for maintaining proper drainage and preventing the sagging of pipes that could potentially obstruct flow or cause damage. While pipe hangers can indeed interact with thermal expansion by allowing some movement, their primary function remains to securely hold and position the piping system within the infrastructure. Other functions, such as sealing connections or insulating pipes, are performed by different components that serve specific purposes within the piping system.
