Unfortunately I suspect I can't hermetically seal the door to my

The best I can do is wrap up the pipe, put draft excluder felt strips
around the edge of the door, and insulate the door itself I think...

any of:

wrap the pipes with (pref) felt lagging
Mount the pipe clips on rubber
box the pipes in
put a rubber mat on the door
draughtproof the door
fit a heavier door
lag the noisy pipes on the floors above or below where the pipe is a
problem, this will also add damping
In some cases you can happily turn down the water flow rate
