A flexible pipe connector 200 for joining a pressurised mains pipe to a service pipe comprises a corrugated longitudinal body portion 202 having a first end, a second end and an internal bore The body portion further comprises a plurality of corrugations spaced along the length thereof, the corrugations defining a maximum internal diameter of the bore at a peak 204 of a corrugation and a minimum internal diameter of the bore at a trough 206 of a corrugation. The body portion has a spigot socket 212,214, at each end 208,210. For a defined volumetric flow rate, the head loss of a fluid flowing through said body portion is no greater than if the fluid were flowing in a smooth bored pipe of the same length and the same internal diameter as the first and second spigot sockets. The minimum internal diameter of said corrugated internal bore is greater than the maximum internal diameter of said first and second spigots. |
