What is the maximum distance between hangers for a sprinkler system composed of 2 1/2 inch Schedule 40 steel pipe?

The maximum distance between hangers for a sprinkler system using 2 1/2 inch Schedule 40 steel pipe is specified by industry standards to be up to 15 feet. This is critical for maintaining the structural integrity and proper functioning of the plumbing system. Proper spacing ensures that the pipes are adequately supported, preventing sagging or misalignment which could lead to leaks or failures in the system.

Using hangers at intervals greater than this can compromise the stability of the pipe, increasing the risk of mechanical strain on the fittings and joints that could arise from thermal expansion or contraction during operation. Maintaining the recommended spacing also helps to ensure that the system meets the relevant codes and standards, which are geared towards ensuring safety and reliability in fire protection systems.
