Unrestrained expansion will be in the order of 27mm.

RE: Pipe expansion help

If you installed the pipe when it was 20 deg C then at 20 deg C it won't see any relative expansion. You need to take the temperature difference from ambient and not the absolute temperature to calculate expansion. The expansion could be anything.

RE: Pipe expansion help

Have to agree with corus, if the pipe is installed at an ambient temperature of 20 degrees, the movement will become +/- 13mm. The change in length given in my previous post is for the whole 10degC range. The Engineering toolbox site is a useful design site, www.engineeringtoolbox.com , with many design cooeficients and other useful information.
