Hello gentleman,

"Universal Pressure balanced metallic elbow expansion bellow"

As known, there are 3 bellows within the unit separated by pipe spools

Could somebody kindly confirm

The axial stiffness values will be provided by the vendor for the whole unit.
While modeling complex model, the above axial stiffness value to be divided between the 3 bellows

Thanking you

Why you do not contact your potential vendor and ask?

Regards,

Thanks danb,

Even though the project is in the beginning stage, i have contacted one vendor and he provided the stiffness value of individual bellows.
