Disclosed is a double-wall pipe 10 for an aircraft fuel system. The double-wall pipe 10 comprises an inner wall 11 defining a first open end, a second open end, and an inner region 14 connecting the first open end to the second open end and via which a fuel is flowable through the double-wall pipe, in use. The double-wall pipe also comprises an outer wall 12 disposed at least in part around the inner wall to define an interspace 13a, 13b between the inner wall 11 and the outer wall 12, that is fluidically isolated from the inner region. The double-wall pipe further comprises at least one barrier 15a, 15b, possibly in the form of rupture discs which are openable to create a passage that fluidically connects the interspace to the inner region. The at least one barrier is configured to open when a pressure in the interspace is higher than a pressure in the inner region. There may be a vacuum or partial vacuum in the interspace.
