What temperature range is suitable for CPVC pipe and fittings?

The correct answer indicates that the suitable temperature range for CPVC (Chlorinated Polyvinyl Chloride) pipe and fittings is above freezing and not exceeding 150 degrees Fahrenheit. CPVC is commonly used in hot and cold water distribution systems due to its ability to withstand higher temperatures than standard PVC. It is important to note that while CPVC can handle temperatures typically up to 200 degrees Fahrenheit, many manufacturers specify a maximum safe working temperature of 150 degrees Fahrenheit to limit the risk of deformation or failure under prolonged exposure to heat.

This specific upper limit helps ensure that the integrity of the pipe is maintained over time, particularly in environments where temperatures may fluctuate or where the piping is subject to thermal cycling. Therefore, the range provided is crucial for ensuring both compliance with safety regulations and the longevity of the plumbing system in which CPVC is used.
