Stud bolt lengths
Stud bolt lengths
(OP)
Hello,
Does anyone know how to calculate
for 26” to 60” flange bolting, Stud bolt lengths?.
Is there a standard formula to figure it out?
I have been using this:
Stud length = (flg thk x 2) + (gasket) + (stud dia. X 2 ¼)
I think my studs are a bit short. I don’t think I like that Idea.
Any help would be great,
Thanks,

Stud length = (flg thk x 2) + (gasket) + (stud dia. X 2) + 0.375
For a 30" 300# RF flange, your formula would call for a stud length of 11-5/16". My table would call for 11-1/4". Yours doesn't seem too short to me.
Keep in mind, the flange thickness must include the height of the raised face. And the gasket thickness must be the compressed thickness (the thickness of the metal ring). The studs must have a full nut of engagement at both nuts. But extra stud sticking out of the nuts will just give you trouble when you try to remove the nuts.
