CPVC pipe and fittings may be suitable for use in areas where ambient temperatures are above freezing and do not exceed _____________.

CPVC (Chlorinated Polyvinyl Chloride) pipe and fittings are commonly used in plumbing and sprinkler systems due to their favorable properties such as resistance to corrosion and high temperatures compared to other plastics. The key factor to consider when using CPVC pipe is its temperature tolerance.

The suitability of CPVC for applications is generally defined by its maximum service temperature, which is determined to be around 150 degrees Fahrenheit. At this temperature, CPVC can maintain its structural integrity and performance without risk of failure or deformation. Exceeding this temperature can result in softening of the material, reduced strength, and potential failure of the system.

While CPVC is indeed rated for use in applications exceeding freezing temperatures, going beyond the 150-degree mark compromises its effectiveness and safety, leading to potential leaks or bursts in the piping system. Thus, the upper temperature limit established for CPVC use is crucial for maintaining a reliable sprinkler system in environments where elevated temperatures could be a factor.
