An elbow section for an insulated conduit comprising an external pipe, an internal pipe, and an insulating layer between the two pipes; a tension strip is looped about the internal pipe and secured to the external pipe as a support for accepting the forces of the flowing medium which act substantially radially outwardly on the internal pipe of the elbow section. Guides allowing to move the strip or the internal pipe only radially outwardly or inwardly along the bend plane of the elbow section are shown too.
