that's gonna be submersed yes??
Yes and No - see below . . .

hopefully in fire or somehihng very hot...
Yes.

That's going to have quite a capacity for whatever your pumping through it.
Yes.
The plan originally was to use 10mm microbore but it'd be difficult to create anything rigid and self-supporting (it's supplied in coils). The 15mm pipe was larger than I wanted but is straight and rigid so lends itself nicely.
Using 10mm pipe would've been harder in the long-run simply because I'd have needed to create a framework to mount the tube on first.
Even then you can still create a smaller radius using 15mm 90* bends over manually bent 10mm microbore.

week points
Not really weak points. I used end feed fittings not only to save a bit of money but also because they're stronger than solder-ring fittings. I've gone heavy on the solder so the "weak points" should actually be pretty tough.

Unless of course you need a high flow rate, in which case a larger bore is a better choice.
The pump I'll be (initially) using has an output pipe of 35mm approx . . . My input is going to be 28mm . . . .
I'm not sure what the long-term set-up will be (that'll depend on the results after testing) but there's the option to fit a valve on the outlet to reduce the flow-rate through the manifolds . . . thus giving it more time to heat.
I hope to be ready for testing this weekend . . . and the tests will be done in the utter, utter worst case scenario so any success will be a major one.
