PED Classification of Jackets
PED Classification of Jackets
(OP)
Hi
I'm trying to complete PED classification for a pressure vessel with limpet coil. I cant decide what way I should analysis the jacket, i.e is it a vessel or a pipe?
Any ideas?
Thanks

RE: PED Classification of Jackets
The jacketed vessel is a pressure vessel, designed per the pressure vessel code (I assume you weld the pipe/halfpipe to the exterior of the shell, don't you?). That is, the inner vessel is designed for internal pressure and additionally to external pressure exerted by the coil.

RE: PED Classification of Jackets
Yes it is a pressure vessel dsigned to EN 13445 3/-1 barg (160/-20 Dec C). The limpet coil (10/-1 barg, 160/-20 Deg C, capacity 552L) is welded to the exterior of the pressure vessel shell.
Vessel is a group 1 fluid.
Jacket is a group 2 fluid.
So what PED group should the jacket be?
Tks
RE: PED Classification of Jackets
The groups you mention stay two different groups.
