Is bending of pipe permitted in accordance with NFPA 13?

Bending of pipe is indeed permitted according to NFPA 13, but it must meet specific criteria outlined in the code. The guidelines ensure that the integrity and performance of the fire sprinkler system are maintained while allowing for flexibility in installation.

For example, when bending pipes, especially when using specific materials such as steel or CPVC, proper techniques and allowable bending radii must be followed to prevent damage or impairment to the pipe. The code provides technical specifications on these practices, including the minimum allowable bend radius and the type of materials that can be bent.

Meeting these criteria ensures that the structural integrity of the system is not compromised, which is crucial for effective fire protection. This flexibility can be especially useful in navigating obstacles or aligning piping without the need for additional fittings, which can sometimes introduce points of failure.
