Abstract
Pipe-in-pipe composite tubular structure having between layers a hardenable filling material associating the layers to enhance the structure mechanical performance mostly in collapse. Prior to harden the filling material, the composite tubular structure can be longitudinally deployable between a folded configuration and a deployed configuration, and has a radial dimension increasing between the folded configuration and the deployed configuration. Such structure is well fitted to be used in oil-well downhole structure and casings or underwater pipeline/flowline.
