Abstract
Rigid tube in helical winding, which is essentially characterized by being formed from a continuous strip of galvanized sheet of different thicknesses and widths, according to the diameter of the tube, wound helically, and joined by a continuous and hermetic seaming that constitutes an outer rib of great resistance for the tube and interiorly smooth and, whose distance between nerves will be determined by the bandwidth.
