ABSTRACT:
For better efficiency in removing scale and deposits in pipes, a high gauss permanent magnet unit, requiring no servicing or external power, mounts on the exterior surface of the pipes for establishing a flux path encompassing a greater portion of the flow path than heretofore feasible. Even more effectiveness results from mounting units in diametrically opposed pairs. The units have a pair of alnico magnetic plates straddling an arc on the pipe surface to focus the magnetic flux into a preferred pattern into the fluid flow path. By blending two permanent magnetic circuit paths from different permanent magnetic materials offering different advantages, a multi-pole, multi-axial magnetic flux generator uniquely distributes and concentrates the magnetic forces for maximum de-scaling effect. Standard units fit different diameter pipes, provide very high fluid treatment flux concentrations over a wide range of pipe cross section area and have long life in the presence of magnetic interference or electrical shock.
