Improvements in the manufacture of reinforced concrete tubes with sheet metal, essentially characterized by the fact that the armature of the tube is constituted by a round that is rolled externally on the sheet metal sheet forming a continuous helix, in order that, when applying to said metallic assembly an internal pressure greater than that which will support the pipe in service, a permanent undulation of the jacket between the turns is caused, achieving the solidation between the sheet metal sheet and the round propeller and the improvement of the characteristics mechanical elements that, after the application of said pressure, will be covered internally and externally with respective concrete coatings of appropriate thickness.
