Primary Differences Between PVC And CPVC Pipes

PVC (Polyvinyl Chloride) pipe is widely used for the purpose of supplying water in irrigation, drainage of soil & waste in buildings, conduits for electrical wires & industrial chemical transportation. In some cases, PVC pipes are also used as water supply pipes in buildings.

CPVC (Chlorinated Polyvinyl Chloride) pipe has been used extensively in fire sprinkler systems since 1985. This material is also used for many industrial and process piping applications as it is corrosion-resistant, easy to install, has superior mechanical strength and long service life.

To start with, the primary difference between CPVC and PVC pipes is the range of temperatures each is capable of resisting. CPVC can handle temperatures up to 200° Fahrenheit, while PVC can only go up to 140° Fahrenheit. If the temperature exceeds these limits, both CPVC and PVC will begin to soften, increasing the risk of joints and pipes failing, which can lead to a failure of the plumbing system.

Other major differences between PVC and CPVC pipes

PVC and CPVC are inherently inert to most acids, bases and salts, as well as aliphatic hydrocarbons. This can extend their service life, often by years or decades. Chemical resistance is a clear advantage for both CPVC and PVC. However, it must also be noted that there is a difference in the chlorine content of the two materials, and that makes CPVC slightly superior to PVC.

CPVC and PVC pipes have the same pressure rating at 73°F (22.8°C), but as the temperature increases, CPVC maintains its pressure rating better than PVC. While PVC can still be used for pressure applications at 130°F (54.4°C), the material can withstand significantly less pressure at high temperatures (above 73°F) than CPVC.
