I need to re-route the pipe running between the oil tank and my 50kW

pipe run info for 10mm (O/D) and I haven't been able to find any other
info. Any suggestions on where to find further info or how to do the
sums on the effect of a few (6 or 8) 6mm restrictions in an 8.6mm bore?
Would the use of flared fittings avoid the loss of flow induce by a pipe
insert? I guess youd need a flaring tool but you cant have too many
tools. ;-)

It would, and that had been Plan A, but I'd discounted it because one of
the points (the end of the existing pipe) would be impossible to get to
with a flaring tool ... and I don't have a flaring tool
Ive no idea how accurate the flaring has to be but I would have thought
that as long as its €śnear enough for the fittings to bolt together the
compression forces with mould the pipe into the correct shape to seal.
(Pure supposition on my part. Could be wrong but Id be tempted to try it
personally. Those with more knowledge of flared fittings on copper might
advise otherwise).
