Engineering ToolBox > Temperature Expansion Coefficients of some common Piping Materials
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.
