Rolled welded pipe is used in some pipeline application. I am more familiar with seamless pipe for higher pressure applications, but I am not an metalurgical specialists. I don't think the pipe fabrication is going to be an issue delaying the pipeline.

It may even be already fabricated waiting for approval to install. This line has been in the works for a long time.

I would guess those seamless pipes are extruded.... I don’t think they would be forged.
