Hi,

For the calculation of a cladded spherical cover the inside diameter (B) should exclude the clad thickness? For example:

800 mm inside diameter spherical head
carbon steel
3,0 mm clad AISI 317L

The inside diameter(B)and flange face inside diameter used in the calculation should be 806 mm?

Thanks,

Fabiano,

Please send your input file to COADE support email address. You can get this address from Help menu -> About PV Elie -> Email Techsupport.

Did you specify the cladding as lining.

fabiano,
It all depends if you can or not include the cladding material in the strength calculations (normally you cannot), refer to ASME SA 264. It also dependes on what inside diameter you have selected for the shell.
In the PV Elite, normally you set the ID as the carbon steel shell and head, excluding the cladding (ie 806 mm, if the shell ID is 806 mm excluding the cladding). Obviously, in your GA drawing, the ID will be 800 mm, not 806 mm, because you have to substract the cladding thickness.
In some cases, as allowed in ASME SA 264, you may include the cladding in the strength calculations, but that's only in special cases.
cheers,
