Massachusetts Journeyman Pipefitter Practice Exam

The primary function of hangers in piping systems is to secure and support pipes. Hangers are essential components that maintain the integrity of the piping system by anchoring pipes in place, preventing them from sagging or shifting under their own weight. This stabilization is critical, as improperly supported pipes can lead to issues such as misalignment, increased stress on joints, and potential failure of the system.

While other functions such as reducing vibration, allowing for thermal expansion, and providing insulation are important considerations in piping systems, they are not the primary function of hangers. Hangers do play a role in wave damping, may incorporate features to manage thermal movement, and can be part of systems that contribute to insulation, but their chief role remains the secure support of pipes to ensure that the entire piping system operates safely and efficiently.
