RE: Flow Control 2 (Nipples)
I've never heard of a PSN nipple though. Ask your local slickline company for more information.
RE: Flow Control 2 (Nipples)
XN nipple is an Otis Flow control nipple with a locking profile, seal surface and a bottom No-Go ring to prevent blanking plugs from falling thro the nipple
Otis Blanking plugs are ran in two pieces, the body is set into the nipple, then the Prong is set into the plug body.
A PSN is a Pump Seating Nipple - ususally these nipples do not have any profiles in them, only a seal surface - When a Bottom hole pump is run the hold down rings seal with a friction fit into the PSN .

RE: Flow Control 2 (Nipples)
as the need for more profiles in a more complex completion I would run multiple X nipples above the XN.
- example: 2 zone completion XN nipple, Packer, On/off c/w X profile, Pup joint, X nipple, 10 joints tbg, 1 blast joint, Sliding sleeve c/w X profile
