B31.3 - 304.3.4 Reinforcement of Extruded Outlet Headers
(OP)
Hello,
It states that hx (height of extruded outlet) must be equal to or greater than rx (radius of curvature). There seems to be a gray area in determining the hx. Can I count the weld as part of the height of extrusion?
Thanks

I don't see any "gray area", only a clearly drawn diagram and set of notes.
What is not clear about it??

Can he include the weld in determining the height of hx?
I said that he can include 1/2 the weld. (Any discrepency caused by including 1/2 the dimension of the root in the calculation of hx should not be very worrisome.)

-Please look at my attached image of how I'm measuring the radius (I took a picture and used AutoCAD). It is difficult to choose where I start and end my arc that I create to determine my radius. There are multiply radii to choose on a single side. What radius do I pick?
-Do you know of any better extruded outlet radii measuring techniques/tools I could use?
Thank you
