Show full version of the posting: Heat Exchanger Heads
The following is the data I have been given for the head of a Heat Exchanger but the problem I have is, I am not seeing a knuckle radius. This is being done in 3D
40" ID x 1/2"PL NOM
2:1 SE W/2" SF
Can anyone help me make this head please? The other end of the Heat exchanger is:
16" OD (.375") NOM.
STD Wall Weld Cap
I know what a heat exchanger is but, I think you need a bit more information to design/draw this one.
Can the requester give you a simple sketch?
I do have a drawing but all I dont have is the radius of the knuckle to put the arc in. I thought there may have been something in the details I listed that I was not understanding or something. I am thinking that the arc should just be proportionate to the other dimensions maybe
Knuckle radius of any fabricated steel project, needs to be at least the thickness of the material.
A knuckle radius for 3/8" thick material should be minimum 3/8".
Am I missin' the point?

correct me if I'm wrong pal, but I usually use the help button when I need help. I don't know about you, just a suggestion! And about 8 more posts and I'm a groupie, so I don't appreciate being called a noob! Thanks
If thats the case, and help solves everything, then why post?
And what sir, would you like to be called?
Novice? Tenderfoot? Greenhorn? Neophyte?
The standards we use give knuckle radius as 0.1 x main diameter. If you look up the standards for designing concave end caps for vessels & heat exchangers they all work on that.
Hope it helps.
