How far apart must hangers be placed on horizontal piping from a standpipe to a hose valve?

The requirement for placing hangers on horizontal piping from a standpipe to a hose valve is crucial for ensuring proper support and stability of the piping system. The correct distance at which hangers should be installed, which is 18 inches, is based on industry standards and guidelines.

In sprinkler and plumbing systems, adequate support reduces the risk of sagging, stress on joints, and potential damage to the piping. Maintaining the specified distance between hangers ensures that the pipes remain secure while accommodating thermal expansion and contraction. Moreover, proper spacing helps in the overall integrity of the fire protection system, as it minimizes the risk of leaks or failures that could arise from unsupported or poorly supported piping.

Understanding the importance of this spacing helps professionals in the field implement these standards effectively, ensuring compliance with codes like the National Fire Protection Association (NFPA) regulations. By practicing proper installation techniques, professionals can enhance the reliability of the fire protection systems they work on.
