What is this pipe? Old Victorian house

[Woodsf]

Hi - we have recently taken away a false basement ceiling and discovered this pipe that
runs along the top and branches off into some of the basement rooms. Any ideas what the pipe? It looks old and redundant, and
Suspect asbestos?

possible, Suspect asbestos wrap.

Agreed looks likely to be asbestos.
Needs testing then could need specialist removal.
