Sorry, no etymologies found.
Any butt-weld fitting or weld-neck flange can be directly welded to any other butt-weld fitting or weld neck flange without the need for any extra piece of pipe (Pup piece) between them.
One such case showed a common control valve station (manifold) which had 11 (eleven) extra and unnecessary "Pup" pieces where butt-weld fittings could have and should have been welded together.
It is just a butt-weld and if I cannot make a butt-weld between these two round, beveled-end, schedule 40 carbon steel (fitting) objects what if I need to join two other round, beveled-end, schedule 40 carbon steel pipes.
For butt-weld fittings the only exception to this is; when there is an overall dimension requirement that is greater than the combined total dimensions of the two fittings.
I would like to see a more complete library of pipe fittings: butt-weld, victaulic, malleable iron, MJ, B&S cast iron -- the list goes on.
I suspect that someone, somewhere was listening to instructions about the make-up of piping assemblies for 2 "(50mm) and smaller screwed or socket weld piping and then mistakenly applied the instruction to all piping including large-bore butt-weld piping.
This specific statement is totally incorrect when applied to 3 "(80mm) and larger butt-weld fittings.
