another idea is to wrap the joints in plastic bags, and then use
expanding foam.
I'm thinking the same way equipment is often boxed for transport -
put it in a box with bags around it, squirt the foam into the bags
and let it expand to fill the gap.

This is what I'd though of for our various joints and plate exchanger,
just not got around to doing it yet.

Cheers,
Webbo.
