We don't give a damn how they do it OUTSIDE.

Looks like a zipper.

Maybe somebody got paid by the foot. :D

I'm pretty sure the pipe itself is priced by the foot. ;)

But I'm going to guess that the constant change in direction helps keep the oil from freezing.

Of course, Thor will be along shortly to clear this up for us. :)

My penis isn't bent and it's never froze.

It's for thermal expansion and contraction. If you look hard, you can see where some cross beams have 4 piles supporting them, instead of 2. Those are anchors and the pipe doesn't move, there. Otherwise, it floats on special shoes on the crossbeams.
