Dear All,

Problem is that I am designing & stress analyzing a 3000 mm dia pipe with 20 mm thick for a steam header as per B31.1 and would also like to model in caesar II.

For end caps / closures I cannot use a flat unstayed plate because thickness in excess of 120 mm comes in calculation. Can I use PG-29 dished heads as per ASME BOILER Sec I code? Are they prohibited or not ? if they are not prohibited how can I model in caesar.

Prompt replies will highly be appreciated.

Regards,
Salz
