Force to form double-curved plates
Force to form double-curved plates
(OP)
We are investigating the feasibility of pressing dome roofs and knuckles for field-erected storage tanks. This would involve forming flat plate to a double-curved shape, requiring the stretching or compression of the plate itself. Is anyone aware of any standard methods or resources for determining the forces required for this? Are there any manufacturers that specialize in this kind of equipment?
Thanks,

If I understand your need correctly, CBI would be one company that would have the capability of forming such plate sections since they have constructed many dome roof tanks, as well as spherical pressure storage vessels.

Also, pressing thin plates into a spherical shape can be difficult, especially for the 3/16 and 1/4 thicknesses. They keep springing back to flat!
