What issue arises from improper spacing of pipe supports?

Improper spacing of pipe supports can lead to compromised structural support, which is the correct answer. When pipe supports are not spaced adequately, it can cause excessive sagging or bending in the pipes. This not only affects the integrity of the piping system but can also lead to increased stress and potential failure at certain points along the pipe.

Proper spacing ensures that the pipes are adequately supported to handle the weight of the piping material, the contents within the pipes, and any additional environmental factors such as temperature changes or vibrations from operating machinery. If structural support is inadequate, it may result in leaks, breakages, or even collapse, necessitating costly repairs and unscheduled downtime of the system.

On the other hand, increased efficiency, enhanced lifespan of the system, and optimal flow rates are generally linked with proper support and maintenance practices, but these benefits cannot be achieved if the foundational aspect of pipe support is compromised.
