Obround Openings

Obround Openings

Obround Openings

(OP)
I recently got back into engineering after four years of teaching math.
Less than three days on the job I was given a horizontal pressure vessel that has two obround openings for firetubes in one of the heads.
Can someone give me some suggestions on how to tackle this problem?
Thanks!

RE: Obround Openings

You might want to take a look at the code references  mentioned in fabrication of hand holes.  This doesn't take into account any reinforcement needed.

RE: Obround Openings

tovi,
as the reinforcement calculation in a head is independent of orientation (unlike in cylinders) you can treat those openings as round with a diameter equal to the maximum width of the obround opening.
