Why are guides necessary in piping systems utilizing bellows joints?

Guides are crucial in piping systems that incorporate bellows joints primarily to prevent offset movements. Bellows joints allow pipes to expand and contract due to temperature changes, which can result in movement that, if unrestrained, can lead to misalignment, wear, and potential damage to the piping system and its supports. By installing guides, the system ensures that the bellows can accommodate thermal or pressure-induced movements without causing lateral or angular displacement. This controlled movement helps maintain proper alignment, thereby extending the life of the piping system and reducing maintenance requirements.

Supporting higher loads and regulating pressure, while important in piping design, are not the main roles of guides around bellows joints. Guides do not typically influence aesthetic appearance, as their primary function is structural integrity and safe operation of the system.
