What is the maximum support spacing for CPVC hangers for 2-1/2" pipe?

The maximum support spacing for CPVC (Chlorinated Polyvinyl Chloride) pipe, specifically for a 2-1/2" diameter, is indeed 9 feet. This spacing is important to ensure that the pipe is adequately supported and can operate effectively without the risk of sagging or damage. Proper support prevents excessive movement and thermal expansion issues that can arise, particularly with CPVC materials, which may be more prone to deformation than metal pipes.

The guidelines for spacing are based on industry standards and the physical characteristics of the material, which dictate how far apart supports can be placed without risking integrity or performance issues. In this case, using supports at intervals greater than 9 feet could lead to potential failures under load or movement. Therefore, understanding and adhering to these support requirements is crucial for maintaining safety and functionality in fire sprinkler systems.
