Abstract

Machine for the continuous production of metal pipes, of the type in which the pipe is manufactured from a metal strip that, by means of rollers and the like, is curved longitudinally until its lateral edges approach each other, where they are joined by welding forming a rectilinear seam according to a generatrix, the pipe being thus formed subjected to a subsequent calibration of its cross section and all said stages being carried out continuously, without interruptions, characterized by being constituted by an elongated frame on which feeders are arranged of metal strip, strip bending means longitudinally, conforming means of cylindrical section approximating the two sides of the curved strip, welding means of said edges with each other, external and internal calipers of said already welded section, radially expanding means from inside for said section and means that exert continuous traction so that the pipe moves according to its geometric axis during its production.
