Fluid transport pipe having a steel tube with a protective lining provided with slots for discharging gas built up under the lining

Abstract

A pipeline for the transport of fluids includes a steel tube intended to receive a flow of fluids to be transported, and an annular lining for protection against corrosion and/or abrasion made of polymer material, and inserted inside the tube. The lining includes a plurality of slots which extend in the direction of their length parallel to a longitudinal axis of the tube and which pass all the way from an inner face to an outer face of the lining, each slot being open on the side of the inner face of the lining prior to the insertion of the lining into the tube, and at least partially closed between the inner face and the outer face of the lining along of its depth once the lining is inserted into the tube.
