I just want to know about, other users experience of bellows expansion joint installed on top of duct riser between the VSS (vortex separation systems) chamber and FCC reactor cyclones.
From my experience it seems to me that the behaviour of the referred expansion joint is very critical for the liability of the reactor.
My expectations for the above expansion joint are coke build up on the convolutions, loss of flexibility, cracking of bellows plies, distortions on cyclones cross-overs and on top dome of VVS chamber. Please share.
