Equivalent pressure for bolted joint

thread292-26170

Equivalent pressure for bolted joint

Equivalent pressure for bolted joint

(OP)
Please, I need to know how to calculate the equivalent pressure acting on bolted joint due to an external bending moment and axial load.

Many thanks in advance.

RE: Equivalent pressure for bolted joint

Check out Thread378-18541.  Good luck...

RE: Equivalent pressure for bolted joint

You may want to revisit the thread mentioned above, as more infor has been added.

RE: Equivalent pressure for bolted joint

Hi , edemarcos:

I´m a spanish Mech. Eng. and I've been working during 10 years in design of heat exchangers and Pressure vessels. Your doubt is totally clearificated in a good book called
Pressure Vessel Design Manual of Robert Moss , in the applicable design chapter about the flanges.
You can obtain Equivalent pressure using the following equation:

Peq = 16*M/(pi()*G**3)+4*F/(pi()*G**2)+P
using M bending moment(in-lb) and F  radial load (lb)

RE: Equivalent pressure for bolted joint

Calidad is absolutely right. BTW, ASME III NB has the same formula.
