What is emphasized about pipe spacing for smaller diameter piping?

The correct response highlights the importance of practical pipe spacing in relation to preventing sagging, particularly for smaller diameter piping. Smaller diameter pipes can be more susceptible to bending or sagging under their own weight or due to external forces, such as the weight of the contents they carry. Adequate spacing and support prevent excessive deflection, ensuring the pipes maintain their shape and function properly.

In practical applications, proper support and spacing are critical for maintaining the integrity of the piping system, as they help avoid mechanical failure and potential leaks that could arise if the pipes are not sufficiently supported. This consideration is vital for installation, maintenance, and overall system reliability, making it an essential aspect of piping design for situations involving smaller diameters.

Other considerations like aesthetics or structural integrity may play a role in piping layout but are not the primary focus concerning smaller diameter pipes, where practical support is the primary concern. Maximizing spacing for structural integrity in this case can lead to issues, as insufficient support may compromise the effectiveness and safety of the piping system.
