If the ends are connected to the sensitive equipment I would put at least one loop since there is no warranty on the zero temperature difference between installation and the operating temperature for either thermal expansion or contraction to keep the loads under allowable.

When you say cold what is the value of it? What will be the atmospheric temperature during the construction of the piping? Will the pipe expose to the direct sun light? There may be others question can rise depending on the process, and its behavior on the piping?

Brainstorm first on process and the conditions that you have, put all the variables together and decide what to do?

Hope it helps.
