Pipe Bend After Fitting
Pipe Bend After Fitting
(OP)
Hello,
This may be a very simple question, but I am looking at creating an alignment for an 8" HDPE SDR 17 pipeline. I am trying to keep to the angles used by pipe fittings, but in some cases I get a 40 degree angle rather 45 degree angle. Is there anywhere I can for formulas for pipe bending after a fitting? Should I should assume the minimum turning radius (I have that formula) for a pipe the pipe after the fitting?
P.S. I have plenty of room for the pipe to turn...
Thanks...

Get a bandsaw large enough to pass the 8 inch dia pipe.
Cut 5 degrees off.
Reprep the joint.

If you can't adjust your start or end points to accommodate a real 45 degree elbow, try inserting a 90 elbow, with the outlet aimed "vertically" up from your x,y plane.
Add a stub lenght of vertical pipe, then another 90. But this puts the second 90 directly above your starting point, except the second 90 CAN be rolled to the 40 degree you want. (Or any other angle actually)
Run the straight pipe from that elbow, now "lifted" in z by the 2x 90 elbows to the desired end point at the 40 degree angle you demand, then add two more 90 elbows.
The first to aim "down" and the second to resume the direction you want.
OK, you've solved one problem, but you have increased fabrication time, material cost, and the flow resistance

If it ain't broke, don't fix it. If it's not safe ... make it that way.
