PVC - Polyvinyl Chloride
PVC is the strongest and one of the most widely used plastic pipe. PVC has poor resistance to solvents and is used for both pressure and non-pressure applications. PVC is approved for potable water systems.
- strong and rigid
- resistant to a variety of acids and bases
- may be damaged by some solvents and chlorinated hydrocarbons
- maximum usable temperature 140oF (60oC)
- usable for water, gas and drainage systems
- not usable in hot water systems

CPVC - Chlorinated Polyvinyl Chloride
CPVC is a chemical modification of PVC, with an extra chlorine atom in its structure that extends the service temperature to about 180 - 200°F (82 - 93°C). Sizes and other properties are very similar to PVC.
| Operating Temp (°F) | Operating Temp (°C) | De-Rating Factor |
|---|---|---|
| 73 - 80 | 22.8 - 26.7 | 1.00 |
| 90 | 32.2 | 0.91 |
