What is the cure time for CPVC 1½" Pipe if the pressure test is set to 200 PSI at an ambient temperature of 50 degrees?

The cure time for CPVC (Chlorinated Polyvinyl Chloride) pipe is influenced by factors like the size of the pipe, the temperature, and the pressure applied during testing. In the case of a 1½" CPVC pipe under a pressure test set to 200 PSI at an ambient temperature of 50 degrees Fahrenheit, the pipe requires sufficient time to ensure a complete chemical bond and cure of the solvent cement used during installation.

At lower ambient temperatures, such as 50 degrees, the curing process occurs more slowly compared to warmer conditions. While CPVC generally cures faster at higher temperatures, a pressure test at 200 PSI necessitates a longer curing period to ensure the integrity of the joints is maintained under stress.

In this scenario, the recommended cure time of 16 hours is appropriate. This timeframe allows for the necessary expansion, contraction, and bonding of the pipe materials under the specified test conditions. Selecting this duration helps to mitigate risks of joint failure during the pressure test, ensuring a safe and effective installation.
