Pipe for transporting fluids with control of the buckling of the internal anti-corrosion liner

Abstract

A pipe for transporting fluids with control of the buckling of the internal anti-corrosion liner includes a steel tube intended to receive a flow of fluids to be transported, and an annular protective lining made of polymer material, inserted in an interference fit inside the tube against an inner surface thereof and intended to ensure protection of the steel against corrosion of the fluids to be transported, the protective lining having, in a cross-section plane, at least a weakened angular portion whose mechanical resistance to radial deformation is lower than that of the remaining angular portion of the protective lining so as to control the angular location and to promote the axial propagation of buckling of the protective lining following a depressurization of the pipeline.
