PVC vs. CPVC or Different between CPVC Pipes and PVC Pipes

There are some key differences between PVC and CPVC Pipes:

Chlorination: The main difference between PVC and CPVC is the chlorination process. CPVC is made by adding chlorine to PVC resin, which improves its heat resistance, making it suitable for high-temperature applications. Temperature

Resistance: PVC can withstand temperatures up to 140°F, whereas CPVC can withstand temperatures up to 200°F. CPVC is more suitable for hot water distribution systems, fire sprinkler systems, and industrial applications that require high-temperature resistance. Pressure

Rating: CPVC has a higher pressure rating than PVC. CPVC can withstand pressures up to 100 PSI, while PVC can only withstand pressures up to 65 PSI.

Chemical Resistance: Both PVC and CPVC have excellent chemical resistance. However, CPVC is more resistant to some chemicals, such as acids and alkalis, than PVC.

Cost: CPVC is more expensive than PVC, primarily due to its additional chlorination process, which makes it more heat and pressure resistant.

Conclusion:

When it comes to selecting between CPVC (Chlorinated Polyvinyl Chloride) and PVC (Polyvinyl Chloride), the decision mainly depends on the intended application. PVC is a widely used material in plumbing, electrical wiring, and construction industries because of its affordable cost and versatility. It is relatively easy to install and has excellent resistance to most chemicals, acids, and alkalis.

On the other hand, CPVC is a modified version of PVC that has undergone a chlorination process to increase its temperature and pressure resistance. CPVC is an ideal material for hot and cold water distribution systems, fire sprinkler systems, and industrial applications. It can withstand high temperatures, up to 200°F, and high-pressure levels, up to 100 PSI.

So, when it comes to which is better, CPVC or PVC, it ultimately depends on the intended application. PVC is an excellent option for low-pressure applications and a more affordable option. CPVC, on the other hand, is more expensive than PVC but provides better performance in high-temperature and high-pressure applications.
