Radial partition device, in particular radial buckle arrestor for a double-walled deep water pipeline

摘要

A device for arresting the propagation of a buckle appearing on an outer tube of a double-walled rigid pipe intended to transport hydrocarbons and consisting of two coaxial tubes. The double-walled pipe is of the reelable type and intended for very great depths and consists of a thick and rigid annular transverse partition fastened to the inner tube and to the outer tube. The partition is joined to the outer tube and to the inner tube by way of an outer and inner sleeve having the same diameter as the outer and inner tubes and fastened to the latter.
