An aircraft fuel vent pipe (1) with a pipe body containing a duct (4) which extends along a duct axis (5) between an open end (6) and a closed end. A burst disc (7) closes the closed end of the duct (4). One or more devices (10-12) are provided in the duct (4), the devices (10-12) being positioned or shaped to enable the burst disc (7) to be visually inspected by looking along the duct (4) through its open end (6), and to modify a sectional profile of the duct (4) transverse to the duct axis so that the sectional profile of the duct changes between different stations along the duct axis (5). The one or more devices (10-12) inhibit the formation of standing acoustic waves in the duct (4).
