Vacuum design of a open end steam piping
Vacuum design of a open end steam piping
(OP)
Hello Friends, Does it make sense to design a blowdown steam piping that is open to atmosphere for full vacuum? it is in SAGD operation where a 24", ANSI 150 class piping is releasing steam and water at 100 psi and 400F during steam gen blow down events to the pond. Rest of the time it is sitting idle open to atmosphere. This line is being designed for full vacuum conditions. As it is open to atmosphere i am not able to make sense of FV requirement. Am I missing anything here?? Thanks for the help.

The lines subject of steam out conditions typically require stress analysis (e.g. Norsok standard specifies stress analysis for all lines with NPS 3" and higher, if they will be exposed to steam out conditions during lifetime).
