How to reduce thickness in Compress?
(OP)
I have a pressure vessel that has an internal pressure of 900psi and temp of 970F. I run the calcs and compress gave me a thickness of 4" for the vessel and 6" for the heads. I just want to make sure that I can not reduce the thickness anymore. I know for full vacuum chambers I can reduce the thickness by using stiffeners.

I can't change my material. It is specified by the customer. Thanks for the input.

I tried using F&D head at first then ellipsoidal. Both of them came out to about 6" thick. A tapered head will possibly be the ending to this vessel.

generally a 2:1 ellipsoidal is just a little thinner than the shell, all things being equal.

I don't use COMPRESS but I did some very quick numbers using ASME VIII, D1 and came up with required thicknesses less than what you gave.
