Improvements in the manufacture of curves for tubular metal pipelines of fluids at high pressure, equally applicable to medium and low pressures, characterized in that the section of tube to be bent is subjected to a progressive heating whose maximum in degrees is applied to the area of generators that, once the referred section has been curved, they must have a minimum development, decreasing in intensity until said heating is practically null in the area of generatrices of maximum development in the aforementioned bending, and because the molecular contraction that in the bending is created in the area of inner semitubal, it is absorbed by spaced wrinkles or ribs that, in progressive projection, are produced in the said inner zone, resulting in absolute uniformity the final thickness of walls throughout the length of the section thus treated, and being that thickness equal to the calculated for the walls of the straight sections of the pipe in line with the pressure of the fluid to circulate through it .
