Abstract: There is described ducting comprising a plurality of interconnectible elongate ducting components (2, 4) which when assembled define an elongate, longitudinally extending internal channel (22) for receiving a pipe, cable or like elongate member, each ducting component having a shaped inner face (14) with a longitudinal recess (20) such that the components can be assembled with confronting inner faces (16, 18), their respective longitudinal recesses being thereby aligned to form the channel, the ducting further comprising tension bands (6) for securing assembled pairs of components to one another, wherein each ducting component is provided with a transversely extending internal cavity for receiving a tension band, the cavity having two open ends so that the band can pass through the internal cavity of one ducting component and though a corresponding internal cavity of an adjacent ducting component in order to secure one to the other, at least part of the band being thereby contained and protected within the ca

Abstract: A pipe assembly comprises a flexible insulating material (16) in contact with the outer surface of the pipe (10) and a plurality of discrete spaced apart buoyant bodies (14) embedded in the flexible insulating material around the pipe. The flexible insulating material preferably forms a continuous layer in contact with the pipe and the buoyant bodies preferably comprise tubular bodies regularly spaced along the length of the pipe assembly. The provision of discrete buoyant bodies embedded within the insulating material allows relative movement between the bodies and enables the pipe to flexible without damaging the buoyant bodies.
