The table below can be used to calculate the expansion of steam pipes at different operating temperatures.

Production Temperature (^oC)	Expansion pr. 100 m Pipe (mm)
66	63
93	96
121	136
149	166
177	203
204	246
232	279
260	323

To avoid unacceptable stress and damage of the pipe lines - its important to handle the expansion properly.
