This invention refers to a magnetic anti-scaling device that can be coupled around piping with fluid flow inside it, comprising an external tube; and a plurality of magnetic arrangements, wherein each magnetic arrangement is formed by a cylindric support and a plurality of magnets circumferentially positioned on the cylindric support: where—in the plurality of magnetic arrangements comprises a sequency of magnetic arrangements placed side by side, and likely to be longitudinally coupled around the piping in an axisymmetric arrangement, so as to form, at least, a concentration plan of magnetic field; and wherein a spacer and an absorber are positioned at each end of the axisymmetric arrangement, and the external tube surrounds the axisymmetric arrangement. The application of a high-density magnetic flow orthogonally to the speed of the fluid to be treated inhibits formation of scales at the internal wall of piping, thus reducing scaling at the equipment upstream.
