What is the maximum spacing between hangers on 1 1/2" thin wall pipe?

The maximum spacing between hangers for 1 1/2" thin wall pipe is specified as 15 feet. This requirement is based on the structural support needed to prevent sagging and ensure the integrity of the piping system. Proper spacing of hangers is crucial in maintaining pipe alignment and minimizing the risk of damage caused by movement or vibrations.

In general, manufacturers' guidelines and industry standards dictate that the hangers must be placed at intervals that will adequately support the weight of the pipe and the fluid it carries, while also considering thermal expansion and contraction. For 1 1/2" thin wall pipe, the 15-foot spacing allows for adequate support while adhering to best practices for installation. This ensures reliability and functionality in sprinkler systems, which is particularly crucial for safety in fire protection systems.
