If you want to counter any heat soak you can do thermal coating, intake pipe wrapping, or even do the gold wrapping stuff.

The expanding part wouldn't be that big of a deal..

Schedule 40 PVC (the white, cheap stuff) @ 3 inches is rated @ 158 PSI operating pressure...

So if you had some piping made that was maybe half that thickness, you'd theoretically be in the 78-80 PSI range for operating pressure. That's @ 73 degrees f.

PVC wouldn't be a good choice for this application, it can't really handle the temps for any length of time, but I just wanted to use it as an example of good thermoplastics' pressure handling characteristics.

At the very least, plastic cold pipes could be used, but the tooling to manufacture them would likely be prohibitively expensive. Same goes for a composite design.
