Seth at HR motors in CA has custom made stainless steel coolant hoses
made for his 2.2 conversions. These have the barb formed right in and
work really well.

FWIW, I've seen people make 'fake' barbs on copper fittings by putting a
circle of copper wire around the end and soldering.  I saw this done
with
a cooling hose fitting that had been custom-made for a Subaru
conversion.
I think they used 14 ga. wire.  The end result is the same, you have a
smooth ridge that the hose clamp, once properly secured, can't be pushed
over.

With a stainless steel pipe, maybe something similar could be done by
welding a wire ring near the end?  I don't think I'd trust a hose
clamped
onto a non-barbed pipe.  I've heard too many stories of them popping off
at inopportune moments.  The problem with risking this on a cooling
system
is the pressure is highest right at the moments when you really can't
afford to lose a hose.
