Which of the following describes the correct orientation for supporting piping?

Supporting piping correctly is crucial for preventing stresses and strains that can lead to joint failure, leaks, or even pipe damage. The correct orientation for supporting piping includes both horizontal and vertical configurations, as pipes can be installed in various orientations depending on the application and system design.

When pipes are installed, they need to be supported at specific intervals to ensure that they remain securely in place and that the weight of the fluid within them does not cause sagging or bending. If only horizontal or vertical supports were used, it would not adequately account for the different ways that piping systems can be arranged or the forces they may experience.

By supporting piping both horizontally and vertically, it allows for a more comprehensive approach to stability. This ensures that regardless of the angle or orientation of the pipe, there will be adequate support to mitigate the effects of gravity, thermal expansion, and any mechanical stresses from the flow of materials through the pipe system. Thus, the chosen answer reflects the multifaceted nature of pipe support systems in real-world applications.
