not really paul the FFA content of the WVO will corrode the pipe and it goes rancid very quickly, especially if warm.
Aluminum is fine though.
HDPE is great but not if over 60 deg c.
some people have copper heat exchangers and they work okay but the chemistry is definately wrong.

you could build it all in copper and have it electroplated .

So what should you make it all from, in an ideal world?
