[ Field Bending ]

Our transmission pipelines don’t travel a straight course.  They go up hills, around corners, and under rivers and roads.

When pipe is manufactured, it’s a straight piece of pipe.  When steel pipe gets welded together, it’s a really long straight pipe.  So, in order to go over hills and around corners, somehow it needs to be bent.  Bring on the bending machine. 

The bending machine has a mandrel and shoes, and hydraulics.  There are engineering principles around buckling thresholds, ovality, strain, and coating flexibility. To get it just right, bending pipe is a science, but almost more of an art.
