What is the minimum spacing requirement for hangers supporting 2 inch CPVC pipe?

The minimum spacing requirement for hangers supporting 2-inch CPVC (Chlorinated Polyvinyl Chloride) pipe is indeed 10 feet. This standard is established to ensure proper support and alignment of the piping system, which is critical for maintaining the integrity and functionality of the sprinkler system.

Proper hanger spacing is necessary for several reasons. First, CPVC is a plastic material that, while durable, can be sensitive to temperature changes and stress. Adequate support helps prevent sagging and stress points that could ultimately lead to pipe failure. Second, ensuring that the hangers are at the correct intervals supports not just the weight of the pipe itself but also any additional load from water or other materials that may run through the pipe.

Spacing hangers too far apart could lead to the pipe bending or sagging under its own weight, increasing the risk of leaks or bursts. Conversely, placing hangers too close together can be unnecessary and may add unnecessary costs and labor to the installation process. Therefore, adhering to the established 10-foot guideline is essential for the effective and safe installation of CPVC pipes in sprinkler systems.
