Abstract
A method for reinforcing a metal tubular structure (1) including the following steps: introducing inside the metal tubular structure (1), a plurality of substantially linear elements (4) having a tensile strength higher than a predetermined value; and injecting a curable filling product inside the metal tubular structure, so that the curable filling product contacts an inner surface of the metal tubular structure (1) and coats the substantially linear elements (4) of said plurality of elements.
