Rectangular Flanges Calculation
Rectangular Flanges Calculation
(OP)
Hi,
I need to calculate an air coolers headers acc. to ASME. I'm using appendix 13 for boxes, but I need to calculate rectangular bolted cover. I have found one thread here posted in 2002 saying that I should use UG-34 and bolt load to calculate acc. APP-2 (for circular flanges).
My question is how to determine G (gasket reaction factor) which is included in formulas for "W"... when my gasket is non circular?
And other thing, is this method using APP-13 for boxes correct?
Thanks in advance

After I have found that book, I saw the calculation and that is it.
Thanks a lot to all.

Be careful when calculating the stress in the bolts for the operating case as unlike circular flanges the bolt loading is not uniform and the bolts in the middle will experience a greater reaction. You should always check the reactions with FEA, many people get caught out by this.
