Many thx for changes 2016 -> 2020
>>Have you calculated the manhole flanges yet? What gasket stress have you used? What gasket material?
We calculated the flanges of the hatchways. I took the data on the gaskets from the book "Coulson & Richardson's Chemical Engineering", page 860, attached

Hi, Ed
In BS 4994 Kmin is 8 (9.2.2). In EN13121 Kmin is 6 or 8 for basic design (table 8).
Material properties is equal to: BS4994 table 5, EN13121 table 3.
But EN 13121 more flex and complex, see properties for WR in table 3.
Conical bottom calculated according to BS is thicker than in EN...
Thank you very much for your reaction to my question.
Ok, I'll try to accept your offer that L = Ls.
Then in the picture below the "short" cone:
L = Ls = 2154 <6 * Dm = 6 * 1000 = 6000
And in this picture "long":
L = Ls = 6053> 6 * Dm = 6 * 1000 = 6000
The vast majority of my cones will be...
Hi
In chapter 10.4.4.2.2 has 2 variant:
a) for short conical shells - L < 6*Dm
and
b) for long conical shell - L > 6*Dm
And has Figure 7, but i dont see L and Dm:
Ok, i think D1 and D2 a draw red pen, so Dm = (D1+D2)/2
What is L? L=Ls? Where i can find L value? L is all length/height of...
