Abstract (en)
An improved system (1) is described for manufacturing welded pipes (2, 12) of different diameters wherein the means (6) used to make the round pipe (2) having one of the above mentioned diameters are mounted, together with the related motor means (3), on a single bench (4), the benches (4) relating to the different diameters being parallel to each other and movable on rails (5) at right angles to the direction of travel of the pipe. Downstream of the means (6) can be situated shaping means (10), adapted to transform a round pipe (2) into a square or rectangular pipe (12), which are advantageously mounted on a further bench (14) movable on further rails (15) at right angles to the direction of travel of the pipe; the shaping means (10) relating to the different diameters are mounted, together with the related motor means (13), on the further bench (14) parallel to each other.
