RE: Removable spool, when?
In addition to the above situations, a removable spool is preferred for equipment isolation for safe entry. A 3 foot spool piece at a vessle nozzle is convenient because you simply remove all but one of the lower bolts and swing the spool down. That connection is now isolated without needing a blind. A less convenient but still preferred alternative is if you have an elbow immediately off the nozzle, put another flange pair on the vertical run and a lifting lug on the elbow for rigging out the piece.

Another application is for clearing of bogged of process lines- particularly high density/coarse applications. Generally it is best to have these on elbows to easy access to high pressure water cleaning in two directions (you can achieve the same result however with a reasonable size stub and flange on the elbow).
