Sprinkler systems that operate above how many PSI have different support requirements?

Sprinkler systems that operate above 100 PSI require different support requirements due to the increased pressure they must accommodate. This higher pressure can significantly impact the design and installation of the system, necessitating enhanced support structures to ensure the integrity and safety of the piping and sprinkler heads.

At pressures above 100 PSI, the forces acting on the piping increase, leading to a greater potential for mechanical failure or damage. Therefore, the support structures must be designed to handle these increased loads and maintain system stability. The design may include more robust brackets, hangers, or support rods and might also require specific spacing and material considerations to handle the dynamic forces experienced during system operation.

Understanding these requirements is crucial for ensuring that sprinkler systems are compliant with local codes and standards, as well as safe and functional in a variety of operating conditions. This knowledge helps in preventing issues such as water hammer or pipe bursting, which can occur when systems are not adequately supported at higher pressures.
