I am looking for u-bend fittings with a round or square cross section.
It's for a heat-exchanger design ... COST-SENSITIVE.
I have put up images, Solidworks generated, of either fitting at -
the first prototype used 3/4" square tubing. In the images linked to
here, center to center distance, between the 2 apertures of the U-bend,
is nominally 4 inches/ 10 centimeters.
But that's very nominally - the design is fluid at this stage. I
really do not want to use custom fabbed parts for the U-bend
transition, at least not for prototypes & LRIP, low rate initial
Material - aluminum, copper, brass, plastic, rubber.
I did a web search for this and am swimming in data for right-angle
transitions. But to get a U-bend out of 2 swept right-angles, I might
need to add a third piece, which increases part count.
I heard about a guy in Arizona with 20 dishwashers in his multi-acre
backyard. I'm hoping there's a surplus or plumbing vendor with these
kind of parts in quantity.
