Kind of a weird diversion there for no obvious reason. I wonder why the pipeline does that?

At a guess I would say it is either a land boundary that they are following, or that the ground for some reason was unsuitable for building the pipeline and they had to go around.

Thermal expansion. It prevents the pipes from having long straight sections that would be prone to buckling.
