What is the primary purpose of using rigid support for pipes over long vertical runs?

Using rigid support for pipes over long vertical runs primarily serves to prevent sagging, stress, and damage to the pipes. When pipes are installed vertically, they are subject to their own weight, and without proper support, they can bend or sag. This situation can lead to several issues: increased stress on joints and fittings, potential for leaks, and even damage to the pipe material itself. Rigid supports maintain the pipe in an upright position, ensuring that it remains stable and that the system operates effectively over time without the risk of failure due to mechanical stress.

Additionally, proper support significantly contributes to the longevity of the piping system. By adequately securing the pipes, you are also helping to maintain the intended flow of fluids, reduce vibration, and avoid misalignment. Overall, the main priority is securing the structural integrity of the piping system while preventing any operational complications that might arise from insufficient support.
