Alaskan pipeline

Here's the pipeline crossing a river.

Notice how the pipeline is sitting so it can move back and forth on the stand and it expands and contracts with the temperature. It is also made that way in case of an earthquake.

These contraptions are to get rid of the heat where the pipe is buried. In other words, they serve as a heat sink.
