Operating Temperature
- is the maximum operating temperatures for plastic pipe materials.
| Plastic Pipe Material | Operating Temperature | |||
|---|---|---|---|---|
| With Pressure | Without Pressure | |||
| (oF) | (oC) | (oF) | oC) | |
| ABS - Acrylonitrilebutadiene Styrene | 100 | 38 | 180 | 82 |
| PE - Polyethylene | 100 | 38 | 180 | 82 |
| PVC - Polyvinylchloride | 100 | 38 | 140 | 60 |
| CPVC - Chlorinated Polyvinyl Chloride | 180 | 82 | 180 | 82 |
| PB - Polybutylene | 180 | 82 | 200 | 93 |
| PP - Polypropylene | 100 | 38 | 180 | 82 |
| SR - Styrene Rubber Plastic | 150 | 66 | ||
