Pipe loops are used to accommodate thermal expansion. I have seen many types and lengths but here is one example:

I am a little unclear on why they can work. With any thermal expansion the stresses on the elbow joints should become very severe and could even lead to fatigue with repeated expansions.
Does increasing the length of the bend (I've some very long bends) lessen the stress on the elbow joints?
Some loops are circular rather than rectangular. What is the advantage, if any, of a circular loop?
Why aren't simpler in-line "sliding" joints or bellows joints used?
