What are pipe "loops"?
What are pipe "loops"?
(OP)
While looking at photographs of a chemical plant, I had noticed that in several places the piping takes a right angle jog, turns back to the original direction, then takes two more turns to be back in line with the pipe. On the photos these were referred to as "loops." What is the purpose? It did not appear that these were put in to avoid obstructions.

Not having the benefit of the photographs you saw I would guess that the "Loops" were for the adsorption of thermal expansion due to high temperature of the pipe lines.

The term "line loop" is usually reserved for a second (or third or fourth) line laid alongside a primary line to alleviate bottlenecks in the system flow. I've never heard why this kind of expansion is called a "loop".
