The curvature of earth and a metal pipe!

I’ve been wondering about the following issue for the past few days, let’s assume all terrain on earth is plain, we have infinite supply of straight pipe sections we can assemble into a very straight long pipe all over the equator, if we observe a small part of the pipe let’s say, 10 or 100 meters it would appear straight, but as a whole, would it continue to be so straight that it would form an increasing angle with the surface as the planet’s surface becomes curved? Or would the pipe become ring along the planet? and in this case, how could it become a ring if it’s all straight pieces of rigid metal pipe? because of the curvature of space due to gravity? or because long things tend to bend in proportion to how narrow or thick they are respect to the lenght?? English is not my mothertongue, I hope i made myself clear enought in depicting the esense of my question. Thank you.
