American made, American invented and just in time for the latest surge in American domestic fossil fuel developments.

Interesting idea. The binding resins, if capable of resistance to attack by hydrocarbons, would make for reliable pipelines for transporting oil and natural gas, and would have “give” also.

What about secondary containment pipe? You can’t move gasoline without it. Plus, I can’t imagine this saving much money using carbon and epoxy. Also, mandrel-wound composite pipe is structurally inferior to pipe centrifugally cast inside a hollow mandrel. When they can come up with a mobile centrifugal casting process then they’ll really have something. And they wont need expensive carbon fiber to overcome the strength compromise. But none of this could work in secondary containment applications.

Carbon fiber is NOT cheap and when it breaks, you need to replace the entire component. It shatters on failure.
Great for F1 car chassis as the shattering absorbs the impact. Then you throw it away and build a new one.

Aereospace Materials Used To Build Endless Pipe

Sounds like a bit of oversell...

It is a real shame when otherwise brilliant engineers worry about "jobs, local economies, indigenous peoples, social justice, green, blah, blah, blah." He does talk about practical engineering objectives -- lower cost, improved performance, shorter construction time, improved reliability, better logistics -- but he just has to toss in "feel good du jour" PC crap to get government dolts to pay attention:

• "...boosting local economies"
• "...creating jobs and boosting local economies"
• "...pipeline project in a developing nation"
• "...workers could make this pipe in their own village"
• "...built faster with the help of local labor"

Reminds me of the village steel mills China tried to create in the 1960s.

Lastly, what NDT techniques does he propose to examine the pipeline material for wall thinning, possible erosion/corrosion, etc? I doubt ultrasound or xray imaging is going to work very well on such composite materials.
