Device for limiting propagation of deformation in double walled pipe transporting hydrocarbons comprises annular partition connected to inner and outer tubes by inner and outer sleeves

摘要

The propagation limiter of a deformation appearing on an outer tube of a rigid double walled pipe (1) composed of two coaxial tubes (2,3) is constituted by a transverse annular thick partition (11). The partition is connected to the two tubes by means of outer (12) and inner (14) sleeves of the same diameter as the tubes.
