What is the maximum vertical spacing in feet for steel hydronic pipe?

• A. 10 feet
• B. 12 feet
• C. 15 feet
• D. 20 feet

Answer: (C)

Vertical support spacing is about keeping the pipe properly supported along its length so it doesn’t bow or stress joints as it heats and cools. For steel hydronic piping, the maximum distance between supports on a vertical run is 15 feet. This limit helps prevent deflection, reduces stress on hangers and fittings, and accommodates the expansion and contraction that occurs with temperature changes. If supports were spaced farther apart, the pipe could sag between supports, potentially leading to leaks or misalignment. So, the maximum vertical spacing is 15 feet.
