Hi,
In my current project, the ambient temp. of piping installation yard is T=21°C which I used it as the ambient temp. in CAESAR.
The max design temp. is T1=80°C (ΔT1=80-21=59°C) and the min. ambient temp. of plant is T2=-36°C (ΔT2=21-(-36)=57°C).
All load cases now are according to T1 which cause a bigger temperature variation.

Could anybody say me that I have to add any new load cases for T2 (since during plant shutdown it will be the case) or I’m in safe range now?

Kind regards.
