Abstract
The present invention concerns a device for heat-insulating at least one sub-marine pipe. The sub-marine pipe includes a heat insulation covering including a material subject to migration, the covering surrounding the pipe and being covered by a sealed protective envelope having a tubular shape and a longitudinal axis of symmetry. The envelope being constituted by a flexible or semi-rigid material able to remain in contact with the external surface of the insulation covering when the latter warps. The device includes at least two sealed transversal partitions, each being constituted by a closed rigid piece traversed by and integral with the pipe and with the envelope.
