Composite pipe, which is essentially characterized by the fact of being established on the basis of the substantial combination of three basic elements, of which two are integrated by two pipes concentric with each other, an internal constituent of the fluid pipeline itself, and an external envelope operatively arranged to protect the internal pipe, as well as a steel braid constituting the third basic formative element of the composite pipe in question, is located between those pipes and established on, around and along the internal pipeline , with the specific functionalities, among others, to give consistency to the whole and prevent the untimely occlusion of the inner pipe by effect of possible external pressures, increasing, at the same time, the resistance of the internal pressure of said inner tube, thus how to make it impossible for the pipes, interior and exterior, to move ra, respectively, by virtue of their adjustment between both and the action of marking in depth that on those exerts said steel braid, whose tupidity is determined in each case in consideration of the resistance required for the inner pipe.
