What is "sway bracing" in sprinkler systems?

Sway bracing refers to a support system designed to secure piping in place, ensuring it remains stable and does not experience excessive movement due to various forces, such as vibrations, thermal expansion, or water hammer effects. In sprinkler systems, sway bracing is critical for maintaining the integrity of the piping network, especially in environments where potential shifts or impacts could compromise the system's performance.

This support helps to protect the pipes from bending or breaking, which could lead to leaks or system failures during operation. Proper installation of sway braces is essential for meeting safety codes, like those outlined in NFPA 13, and ensuring the longevity and effectiveness of the sprinkler system.

The other choices do not accurately represent the purpose of sway bracing; it is specifically related to structural support, not enhancing water flow, aesthetics, or adjusting angles of the sprinkler heads.
