Discover the secret to accurate bolt load calculation

why Hp is 2 X b ?

[@shridharjakhalekar5002]

Why there is multiplication by 2 in Wm1 but not in Wm2?

[@majidalkhayari5572]

I do not understand from where the 2 came in Wm1 eq but I do understand why it is not there in Wm2 eq.
G×pi = mean circumference of the gasket so when he turned it into a rectangle it became the rectangle length.
b is gasket width, practically it is OD-ID of gasket if I am not getting this wrong

2 faces of the gasket

[@atishjain7093]

No 2 gasket faces does not means 2 times force will be taken. Reaction force always be there.

Hey dear,
So basically according to what I know "b" is just the half width of the gasket. hence to calculate the area we have to take 2b * circumference.

@@fahimansari156 but why there is no 2 in wm2 equation? just pi*G*b*y

[@jasonligo895]

I would think that adding Wm1 and Wm2 would be the total force that the bolts would need to exert in order for a gasket to not leak at a specific operating pressure?

[@ScootoideLearning]

Both are different cases.

[@lostinlife5154]

Abhishek Sir...
I wanted to ask why value of "m" is > 1
I mean how gasket can apply more pressure on flange than it is subjected to.
I mean if internal pressure is 5 kg/cm2 how gasket (having m=3) is applying 15 kg/cm2 ?
Logically it should damp some pressure. Right ?
