Minnesota Journeyman Sprinkler Fitter Practice Exam

Question: 1 / 550

What is the maximum length a branch line starter piece can be without a hanger?

4 ft

6 ft

The maximum length a branch line starter piece can be without a hanger is set at 6 feet. This guideline is established to ensure that the branch lines are adequately supported to prevent sagging, bending, or stress on the piping system. Without proper support, longer sections of pipe can experience excessive movement or load, leading to potential failures or leaks in the sprinkler system.

In sprinkler system design, it’s essential to maintain structural integrity through proper support systems. By limiting the length to 6 feet, it allows for optimal alignment and minimizes the risk of complications that could arise from inadequate support. Each pipe segment should be secured appropriately to maintain the effectiveness and safety of the entire sprinkler system.
