Thermal Expansion of Steam Pipes - inches
When a steam pipes is heated from surrounding temperature to operation temperature - it expands

The table below can be used to calculate the expansion of steam pipes at different operating temperatures.
| Production Temperature (oF) |
Expansion pr. 100 ft Pipe (inch) |
| 150 | 0.75 |
| 200 | 1.15 |
| 250 | 1.6 |
| 300 | 2.0 |
| 350 | 2.4 |
| 400 | 2.9 |
| 450 | 3.3 |
| 500 | 3.8 |
To avoid unacceptable stress and damage of the pipe lines - its important to handle the expansion properly.
