A method of manufacturing a spherical pigging device for passing through a pipeline by forming a water soluble spherical core, affixing numerous magnets to the surface of the core, suspending the core within a spherical mold, pouring a liquid between the mold and the core that will cure to form a spherical body, removing the spherical body and dissolving the core to leave a hollow spherical body with the magnets encased within it.

Method of manufacturing a spherical pigging device

A spherical pigging device for passage through a pipeline wherein magnetic sensors are located exterior to the pipeline. The device includes a non-ferrous spherical body. A plurality of magnets, each magnet having its poles radially aligned, are divided into two groups, a first group having its north poles facing the center of the spherical body and a second group having its north poles facing away from the center of the sphere.
