The jog in the pipeline is to allow for thermal expansion isssus. Were there not the expansion joints, due to forces created by temperature changes the pipe would either pull itself apart at the low extremes, or it would expand, distort and rip itself off it's foundations.

Check out <a href= "">Alaska Pipeline</a> for more on the pipeline.
