What is the maximum allowed distance between piping supports for NPS 2 piping when run horizontally?

For NPS 2 piping that is run horizontally, the maximum allowed distance between piping supports is generally specified as 10 feet. This guideline is crucial in ensuring the structural integrity and safety of piping systems. Proper support prevents excessive sagging or deformation under load, which could lead to leaks or other failures.

This distance is determined by factors such as the weight of the pipe, the contents it carries, and the potential for thermal expansion or contraction. Ensuring that the piping is adequately supported within this distance helps to maintain alignment and avoid undue stress on joints and fittings.

In the context of the options provided, 10 feet is consistent with industry standards for NPS 2 piping and is a recognized practice within various building and mechanical codes, emphasizing the importance of structural soundness in piping installations.
