Expansion coefficients of some common materials used for calculating pipe temperature expansion of pipes and tubes can be found in the table below:
| Material | Expansion Coefficients | |
| "Inch Fahrenheit" (in/inoF x 10-6) |
"Meter Celsius" (m/moC x 10-6) |
|
| Aluminum | 12.8 | 23.1 |
| Carbon Steel | 6.5 | 11.7 |
| Cast Iron | 5.9 | 10.6 |
| Copper | 9.3 | 16.8 |
| Stainless Steel | 9.9 | 17.8 |
| ABS Acrylonitrile butadiene styrene | 35.0 | 63.0 |
| HDPE High density polyethylene | 67.0 | 120.0 |
| PE Polyethylene | 83.0 | 150.0 |
| CPVC Chlorinated polyvinyl chloride | 44.0 | 79.0 |
| PVC Polyvinyl chloride | 28.0 | 50.4 |
Note! The high expansion coefficients for the plastic materials makes plastic piping and tubes extreme sensitive to change in temperature. Always pay attention to plastics were temperature varies.
