What is the maximum vertical spacing allowed for steel hydronic pipe?

The maximum vertical spacing allowed for steel hydronic pipe is indeed specified, and a spacing of 15 feet is considered standard practice within the industry. This regulation ensures that the pipes are adequately supported to prevent sagging or undue stress on the system, which could lead to issues such as leaking, damage, or reduced efficiency.

In hydronic systems, the proper support of piping is crucial for maintaining system integrity and performance. Spacing them too far apart may compromise the stability of the piping and could also lead to vibrations that may cause wear over time. Accordingly, a maximum vertical spacing of 15 feet strikes a balance between support and practicality, allowing for installation ease while ensuring the pipes remain securely positioned.

While the other options suggest greater spacing, adherence to the 15 feet standard helps to ensure the reliability and longevity of the piping system in various temperature and pressure conditions typical in hydronic applications.
