According to NFPA 13, what is the minimum bending radius for pipe with a diameter over 2½ inches?

The minimum bending radius for pipe with a diameter over 2½ inches is specified as 5 times the diameter according to NFPA 13 standards. This requirement is crucial because it ensures that the integrity of the pipe is maintained during installation and operation. Pipe bending that exceeds this radius can lead to kinking or damage, which can compromise the performance of the fire protection system.

Maintaining a proper bending radius is vital for ensuring that fluid can flow smoothly through the pipe without restrictions or turbulence, which can impede the effective functioning of the sprinkler system. Such guidelines help prevent any potential issues related to pressure drops or obstruction in the system, thereby enhancing overall reliability and safety in fire suppression scenarios.
